No, we're not drunk -- not right now, anyway. There really does exist, out the in the world, a 1984 Toyota Celica Supra Boss 302. Meaning someone plunked a 302 cubic-inch mill into a 1984 Toyota Celica Supra.

The "Boss" moniker is a Mustang reference that might be a bit of a stretch, but there is a 5.0-liter engine from a 1988 Mustang under the hood.

The transmission is also Mustang-related -- it's a Borg Warner 330 five-speed manual, which is actually an upgrade over a stock Mustang five-speed from 1988.

The car has a custom dash and the seller says it runs well. The outside looks clean from photos, though the sunroof doesn't work -- and the seller was planning on welding it shut anyway.

Apparently there are only 700 miles on this build.

Tim Healey

Tim Healey grew up around the auto-parts business and has always had a love for cars — his parents joke his first word was “‘Vette”. Despite this, he wanted to pursue a career in sports writing but he ended up falling semi-accidentally into the automotive-journalism industry, first at Consumer Guide Automotive and later at Web2Carz.com. He also worked as an industry analyst at Mintel Group and freelanced for About.com, CarFax, Vehix.com, High Gear Media, Torque News, FutureCar.com, Cars.com, among others, and of course Vertical Scope sites such as AutoGuide.com, Off-Road.com, and HybridCars.com. He’s an urbanite and as such, doesn’t need a daily driver, but if he had one, it would be compact, sporty, and have a manual transmission.

I was excited to click on this link, then very depressed with the result.

Normie I like Corey's posts because his earnest effort makes for a civilized comment space.And I get more information and curiosity from his lavish coverage of a car that was never "me" than from any articles I've seen about my cherished tall & boxies.
Bookish So some lawyer comes up with a scam to shake down the auto industry and the NYT makes it an ethical crusade against Ford. And you repeat it moralistically and uncritically.

AZFelix This generation of Cadillac articles also shows consistent placement of photos relative to the corresponding text.
Biff Finally the chickens have come home to roost. I have been saying this for three years: just wait until the EV’ers have to pay the road tax. Lets not forget that it’s California we are talking about and they have never met a tax they didn’t like. Plus it’s “the rich” buying new cars so its a double “lets tax’em!” The solution is simple enough. Have EV’s go into emissions stations as part of license plate renewal. Except here record the milage and get a bill for the cost. The rate should be around 1.5X the comparable gas size vehicle due to added weight. Lets watch the progessive politics swallow this one!
