The Mazda Mx3 A Hidden Gem Worth Buying

Why You Should Actually Consider a 90s Mazda Coupe

The Mazda MX-3 sits somewhere between the Miata and the RX-7 in the brand's lineup history, but nobody ever talks about it. Most people scroll past them at car meets without a second glance. That is precisely why they are affordable right now. I picked up a 1993 MX-3 V6 back in 2019 for twelve hundred dollars. It had eighty thousand miles on it and the previous owner had clearly just kept the thing running without maintaining anything. It ran fine after I replaced the spark plugs, the wires, and the fuel filter. What I did not expect was how civilised the cabin felt compared to a contemporary Civic Si or even a 1994 Integra. The seats are supportive, the HVAC actually works properly, and the dashboard layout is sensible. Mazda engineered this thing like a proper daily driver disguised as a sports car.

Here is the straightforward breakdown of what you are actually getting into. The MX-3 came with three engine options across its production run from 1992 to 1998. The base model had a 1.6 litre four-cylinder producing roughly 110 horsepower. It was adequate but frankly boring. The 1.8 litre DOHC version, called the 18A in some markets, bumped output to around 138 horsepower and felt noticeably quicker. Then there is the 2.0 litre V6, which produced about 140 horsepower. The V6 sounds nice, runs smoothly, and the exhaust note is decent, but the power gain over the 1.8 is marginal. The real advantage of the V6 is torque and the way it pulls without needing to rev hard. All models used a five-speed manual transmission except for the very early US-spec cars that came with a four-speed automatic, which you should actively avoid. The later five-speed auto, designated the DP4A-EL, is actually quite reliable if you change the fluid every thirty thousand miles.

The suspension is a MacPherson strut front and a multi-link rear setup. It is more complicated than a Miata's and that complexity shows up when things break. The rear lower control arm bushings wear out around eighty to one hundred thousand miles. You will notice it as a vague clunk when going over bumps at low speed. Replacing them costs about sixty dollars per side in parts if you source them from RockAuto, but labor is a pain because you have to drop the subframe. I did it myself with a jack and a socket set in about three hours. The all-wheel-drive system is a viscous coupling unit, not an active electronic system. It engages automatically when the front wheels lose traction. It works fine for light rain and snow but do not take it off-road. The rear differential is a simple open type and the rear wheels will spin freely if one loses grip. I learned this the hard way when I got caught on a gravel road and ended up pinned against a tree trying to figure out why the car would not move forward despite the engine revving. Body issues are minimal if you find a clean example. The glass hatch is a single piece of acrylic that scratches easily and yellows over time. Ozone cutting is the standard fix if yours gets bad. The steel underneath is generally sound unless the car sat in flood water at some point. Check the trunk mat and the spare tire well for rust. Check the rocker panels where they meet the wheel arches. Check the door sills. Those are the usual rust spots on any Mazda from this era.

Electrical gremlins are the main headache. The EGI connector, which plugs into the ECU near the firewall on the driver side, corrodes internally and causes intermittent no-start conditions. Your car might start fine one morning and refuse to crank the next. The fix is to replace that connector or at minimum clean the terminals with electrical contact cleaner and apply dielectric grease. I spent two Saturday mornings diagnosing a no-start that turned out to be nothing more than a corroded pin in that connector. A multimeter and some patience saved me from buying a new ECU that I almost ordered. Another electrical thing to check is the instrument cluster grounds. If your gauges flicker or the odometer freezes at a random mileage, tap the dashboard lightly while the engine is running. If the gauges respond, you have a bad ground strap that runs from the dash to the chassis. A quick wire braiding repair fixes it permanently. Parts availability is mixed. Engine internals for the 1.8 are available from Mazda and third-party suppliers. The V6 is trickier because some US-market versions have different cam profiles and intake manifolds than the JDM models. If you are sourcing parts for the V6, always confirm your engine code by checking the badge on the valve cover or the VIN. The E3 engine code is the 2.0 V6. The FP engine code is the 1.8 DOHC.

Interior trim pieces are hard to find new. The dashboard plastic cracks from sun exposure, especially across the top where the windshield meets the dash. You can buy replacement pads from specialty forums and vendors, but they cost around two hundred dollars shipped. I wrapped mine in Vicuna leather from a upholstery shop and it cost me about eighty dollars in material. Maintenance intervals are straightforward. Change the oil every five thousand miles. Use 5W-30 synthetic. The timing belts on the 1.8 and V6 should be replaced every sixty thousand miles. The 1.8 has an interference engine, so if the belt jumps or breaks, you will bend valves and likely need a full head rebuild. That is a four-thousand-dollar job done right. Do not skip this service. The V6 has the same requirement. Budget two hundred dollars in parts and eight hours of labor if you do it yourself, or six hundred dollars at a shop. The water pump and thermostat should go in at the same time as the belts. They are cheap and easy to reach. The crankshaft pulley bolt is a one-time-use fastener. Replace it. I stripped one trying to reuse the old bolt and had to drill it out, which took three hours and a damaged pulley.

Brakes are standard size. Front rotors are 282 millimetres and rears are 256 millimetres. The calipers sometimes stick if you live somewhere with road salt. Bleed them or rebuild them every few years. The ABS module on later models is expensive to replace, but the system rarely fails. The main issue is the wheel speed sensor rings corroding, which triggers the ABS light. Cleaning or replacing the ring costs about forty dollars per corner. Insurance is cheap because these cars are not valuable. Expect maybe sixty to eighty dollars a month for full coverage on a clean example depending on your location and driving record. Registration varies by state but these are old enough that most places do not require smog testing anymore. Real-world fuel economy is around twenty-eight miles per gallon city and thirty-six highway for the 1.8. The V6 drops to about twenty-five city and thirty-two highway because the car weighs roughly three hundred pounds more. Neither number is impressive by modern standards but it is respectable for a car this size and era.

Here is a detail most sellers will not tell you about. The MX-3 uses a unique steering rack input spline that is not interchangeable with other Mazda platforms. When the rack seals leak, you cannot swap in a rack from a Miata or a Protegé like you might expect. You have to buy an MX-3-specific rack. New aftermarket racks from companies like Cloyes exist but the rubber bushings on the cheaper units fail within twelve months. I recommend rebuilding your existing rack with a quality kit from Dorman or simply replacing it with a used unit from a junkyard and rebuilding it yourself using Gates seals. The total cost comes to about one hundred and fifty dollars in parts and two hours of work. Another thing to watch for is the automatic transmission cooler line routing on V6 models. The braided line runs along the frame rail and rubs against a bracket. Over time the insulation wears through and the line chafes against metal. I found this after a leak left a puddle under the car after a drive. The fix is to route the line with a loom wrap and add a silicone guard where it contacts the bracket. Costs about fifteen dollars and thirty minutes. If you are looking at buying one, here is what I would prioritise. Find a 1995 or later model. The early cars had more electrical issues and the interior plastics were softer and cracked faster. A post-1995 car has updated seal materials and slightly improved build quality. Aim for the 1.8 DOHC manual if you want the best balance of fun and reliability. The V6 is nicer to drive but the extra complexity and marginal performance gain do not justify the hunt for parts. The all-wheel-drive models are rarer and command a premium that is not worth paying unless you live somewhere with heavy snow.

Avoid cars with aftermarket exhaust systems that have been drilled and taped together. People who modify these cars tend to drive them hard and neglect maintenance. A stock or near-stock example with a complete service history is far more valuable than a loud modified one with no records. Search terms that work are "MX-3", "MZ3", and sometimes "Madiza MX3" because casual sellers misspell it. Check Craiglist, Facebook Marketplace, and the MX-3 registry forum at mx3.org. The community is small but active and members will often know if a car being sold has known issues. Pricing is still low compared to Miata values. A decent 1.8 manual runs anywhere from two thousand to four thousand dollars depending on condition and mileage. A clean V6 automatic in good shape might ask five thousand. Anything above six thousand is probably overpriced unless it is a low-mileage survivor with documented maintenance. Prices have been creeping up slowly over the past few years as people rediscover 90s Mazdas, but we are not at Supra pricing yet. The window is probably still open for another two or three years before these become unaffordable for most buyers.

The MX-3 is not a fast car by modern standards. It will not embarrass you at a traffic light against a Civic Si or a Focus ST. It is however a well-built, comfortable, visually distinctive car that handles predictably and costs almost nothing to own. That combination is rare. Most affordable sports cars from the 90s are either fragile, ugly, or both. The MX-3 is neither. It is just forgotten. That is the only reason you should care about it.
