How about the 1976 Plymouth Feather Duster? Given that gas isn't getting any cheaper, the idea of a 36 mpg highway car with fastback muscle car-ish styling might be at least a little appealing. Sure, it's dog slow and about as refined as a hammer, but unlike most malaise-era guzzlers, at least you could afford to…

"These taillights mirrored brake and turn functions of the normal taillights, but not the nighttime taillights." Ah, Wikipedia, will you never cease to amaze me?

1978 Oldsmobile Toronado XS. The XS model had a weird wraparound rear window, and there were just under 2,500 made. It's rare, it's from a defunct marque, and it's unquestionably maliasetastic.

Soft, Corinthian leather... In Cordoba, I have what I need.

Maybe not exactly horror, but the '71 Valiant from The Duel got some major screen time in the movie.

I LOVE Zanardi's pass on Bryan Herta in the corkscrew at Laguna Seca. Sure, it was a ridiculous banzai move, and probably technically illegal as he cut the right hander at the bottom of the corkscrew, but still...ballsy.

100+ mph on a public highway, passing a cop in the median, Dukes of Hazzard-ing into a bridge, causing car to disintegrate, and living to tell the tale!

Not that the 917K isn't cool, but the record on the Mulsanne is actually held by the Peugeot WM P87, "Project 400," which broke 400 km/h.

Also, and more in the spirit of the question, the Chrysler Airflow.

The 1940 Oldsmobile with Hydramatic Drive. It was the first production car with an automatic transmission, which, at the time, was brilliant! However, like an invasive species, the prindle took over, and now cars with clutch pedals are as rare as hen's teeth.

Since I can't nominate "all postwar Studebakers," I'll go with the Avanti.

I don't think these aliens are friendly.

On the outside, it looks more like a luxury car for the replicant who's finally made it big.

Perhaps not so much on the outside, but the Aston Martin Lagonda's interior, with its dual-CRT dash, looks like the cockpit of a spaceship from a low budget 80's sci-fi flick.

Ah, intergalactic ducks.

I'd say the 959, but I'm no robber baron. An Alfa Brera, though, would have been within my means.

How about the plastic composite wheels that were available as a factory option on the Jalopnik Fantasy Garage resident Citroen SM?

Looks like Slotted Mags, Torque Thrusts, and Magnum 500s are taken. I'll throw out BMW M-Parallels.

If we're talking about the 70's idiom of "Personal Luxury," the rolling whorehouse that is the Stutz Blackhawk takes the cake.

I always liked the art deco gauge faces on '48-'49 Hudsons.
