Used Mazda Millenia Buying Guide: 1995-2002 V6 and the Miller-Cycle S

A used Mazda Millenia is a 1995-2002 front-drive luxury sedan with a four-speed automatic and one of two V6 engines: a 170-hp 2.5 in the base car, or a supercharged 210-hp 2.3 Miller-cycle engine in the S. The base car is the simpler buy. The S is quicker and more interesting, but it's a rare, complicated engine on a car that's now 24 to 31 years old. Don't trust a clean recall search on this one, because NHTSA's recall lookup errors out for the Millenia; check the VIN with Mazda directly.

I read Consumer Guide's used-car file on the 1995-2002 Millenia, the Los Angeles Times review from June 1994, Car and Driver's 1994 comparison test and Mazda's corporate history timeline, then tried NHTSA's recall data for every model year, all on Oct 20, 2026.

What the Millenia is

Consumer Guide says the Millenia went on sale in spring 1994 as an early 1995 model, sized and priced between the 626 and the 929. Car and Driver's comparison test notes it was originally scheduled to be sold under Amati, Mazda's cancelled luxury brand, and the LA Times called it "the luxury-sedan-that-never-was." Three versions launched: base, base with leather, and the S. Every Millenia had a four-speed automatic; no manual was offered. Dual airbags, antilock brakes and automatic climate control were standard, and the S added traction control.

The S engine is the reason people still search for this car. Car and Driver explains it as a 2.3-liter version of the regular car's DOHC V6, "Millerized" so its compression stroke is shorter than its power stroke, with a Lysholm supercharger to make up the difference. Mazda's own timeline dates its first Miller-cycle car, sold overseas as the Xedos 9 and Eunos 800, to October 1993. C&D ran 0-60 in 7.7 seconds in an S; Consumer Guide timed a base car at 9.4 seconds and an S at 7.8. The LA Times reviewer liked the car but wrote that the "Miller-cycle benefits [are] not worth trouble." That was in 1994, with a new car under warranty. Think about what it means now.

Year-by-year changes worth knowing

1997: reflector headlights, and numerically higher final-drive gearing on base and L models for better low-end response.
1999: a $2,500 to $5,500 price cut, revised grille and taillights, new wood and chrome trim, and one-inch larger wheels.
2000: remote keyless entry standard and steering-gear revisions aimed at better stability. Mazda's 2000 price sheet, reprinted by Consumer Guide, lists the base car at $25,415 and the S at $30,415.
2001: standard front side airbags and restyled front and rear ends.
2002: no significant changes in the final year.

If side airbags matter to you, that makes a 2001-2002 car the target. Consumer Guide also lists NHTSA's frontal crash rating for a 1999 Millenia at four stars for the driver and five for the front passenger.

Known trouble spots

Consumer Guide's trouble list is mostly early-car stuff: a metallic tapping noise on some 1995 engines fixed with a new friction-gear spring on the camshaft, a hard-to-turn ignition key from a mispositioned steering shaft (1995), an off-center steering wheel (1995), and fogged headlights from kinked drain hoses (1995-96). The one that runs the whole production span is a check-engine light caused by carbon buildup on the exhaust valves of the 2.5 engine (1995-02). Its road test also mentions harsh, abrupt downshifts when you floor it, poor over-the-shoulder visibility from wide roof pillars, and a high tail that makes parallel parking awkward.

What I couldn't verify is the cost and availability of parts for the S engine's supercharger today. Before you buy an S, call a Mazda parts counter with the VIN and price the supercharger-related parts you'd most likely need. If the answer is "discontinued," you know what you're signing up for. Honestly, a well-kept base car with records is the safer daily driver.

Recalls: why you need the VIN here

When I queried NHTSA's recalls API for make MAZDA, model MILLENIA on Oct 20, 2026, every year from 1995 to 2002 came back with an HTTP 400 error and zero results, even though NHTSA's own model list includes the MILLENIA name. I then searched NHTSA's downloadable recall files and found no campaign listed under MILLENIA at all. Mazda's 2015 ignition switch recall, 15V674, lists the 626, MX-6, MPV, Protege, 323, MX-3 and 929, but not the Millenia.

That doesn't prove a given car is clean. It means the free lookup won't help, so have a Mazda dealer run the VIN, and read our Mazda recall check by VIN guide for how. The Mazda VIN decoder will also tell you if you're looking at a base car or a real S.

Checking the car's history

Consumer Guide's 2014 good-condition range was $1,400 to $4,800, and that old number tells you how cheaply these trade. Cheap cars attract curbstoners and patched-up salvage cars. Run the VIN through NMVTIS for title brands, then get a CARFAX or AutoCheck report for accidents, owners and odometer readings. If the seller hands you a printed report, pull your own anyway.

About cost: CarVins is a licensed CARFAX and AutoCheck reseller and isn't affiliated with CARFAX, AutoCheck, Experian or Mazda. As of late October 2026, a single report through us was about $5.50 for guests or $4.50 for members, with both reports bundled for about $6.75; direct retail is roughly $39.99 to $44.99. Look at the checkout total before you confirm.
