Although my sister-in-law's now-ex-husband, let's call him "Mike" to protect the guilty, had a company car he could use personally—within reason, I have to imagine—back when we were all still living on Long Island, he splurged on a Mazda RX-8. That would have been around 2007 or 2008. This basket case of an RX-8, which is the same color as his was, is a 2004, and it's for sale about an hour south of the Triple Wide. The asking price is $1,100, marked down from $3,000.
Oooph. That's quite the price cut, and not a good sign. Oh, they're firm on price too. "Don't be low-balling me, bro. No trades. Cash only."
Apparently, according to the seller, it's rebuilt engine from a 2007 RX-8 only runs when it's cold and needs its apex seals replaced, which would be a fairly expensive repair. Mazda did issue service bulletins covering hard-start/no-start conditions on early RX-8s related to low compression, including cases where carbon accumulation could cause the apex seals to stick in their grooves. Apex seals perform a function similar to piston rings in a conventional piston engine.
At the heart of the RX-8 is its Wankel rotary engine, developed by German engineer Felix Wankel and NSU, a West German automobile and motorcycle manufacturer. Buyer of this car gets an after-market cold air intake. Mazda licensed the technology in 1961 and became by far its most famous automotive champion. Mazda introduced its first rotary-powered production car, the Cosmo Sport 110S, in 1967 and continued developing the engine for decades.
Mazda eventually became synonymous with the rotary. There was the RX-2, RX-3, RX-4, RX-5, RX-7 and, finally, the RX-8. The RX-7 became the most famous of the bunch, but the RX-8 was Mazda's last rotary-powered sports car until production ended in 2012. More precisely, it was the last Mazda powered exclusively by a rotary combustion engine; Mazda eventually brought the rotary back in 2023 as a range extender in the MX-30 e-Skyactiv R-EV.
There were many manufacturers interested in the Wankel engine, but they ultimately decided against using it after discovering that it wasn't particularly fuel efficient and was difficult to tune to meet ever-stricter emissions standards in the United States and abroad. General Motors developed its own rotary program and considered using the engine in the subcompact Chevrolet Vega. American Motors designed the Pacer around the assumption that it would be powered by a Wankel supplied by GM. When GM abandoned its rotary program, AMC was left to shoehorn its inline-six into the Pacer instead.
What I liked about Mike's RX-8 from the handful of times I drove it was its handling. So fun. It was one of those cars that seemed to be hard-wired to your brain; you think it, the car does it. What was challenging was the rotary engine. And, frankly, the look of the car.
With only 1.3 liters of displacement and, in six-speed manual form, 238 horsepower, the RX-8 could be a dog around town. A dog that needed to run to live up to its performance potential—and run to the tune of 9,000 rpm. Not something you're going to be able to do often on traffic-clogged Long Island roads. Mazda rated the 2004 six-speed manual at 238 horsepower at 8,500 rpm, with a 9,000-rpm redline; the automatic made 197 horsepower.
Aesthetically, it's funny how poorly these cars' intrinsic weirdness—which was construed as cool, cutting-edge and innovative when new—has aged. Never a good-looking car in my opinion, it was certainly unique and innovative and, when flogged properly, was quite the high-performance car. As most performance cars are, though, as daily drivers they rarely work, despite however much mental gymnastics you do to convince yourself that they do.
Mike didn't hold onto his RX-8 for very long. Impulsive and impatient, although he used the proceeds from the sale of their Long Island house when they moved to Chicago to pay off the balance of the loan on the RX-8, he had grown tired of the car's quirks and idiosyncrasies and used its trade-in value as a down payment on a lease on an Acura MDX.
Yeah. That's yikes-on-top-of-yikes. When some people say they're "not good with money," my sister-in-law and her ex-husband are "Exhibit A," Your Honor.
By ditching his RX-8 relatively early on—I think he had it less than two years—he did get rid of it before it became a maintenance nightmare. The Wankel burns oil by design; the RX-8's oil-injection system deliberately feeds oil into the combustion chambers to lubricate the seals. That's normal for a rotary, but it also means the owner has to keep a close eye on the oil level. In one long-term test, Car and Driver found that its RX-8 consumed roughly a quart every 3,600 miles—far more than Mazda's system was designed to use.
My sister-in-law and her now ex-husband made a number of eye-opening financial faux pas over the course of their stormy almost 27-year marriage, "the RX-8" is just one example. They divorced in 2025.
