I'm not sure it qualifies for the luxury requirement but the AMC Eagle SX/4 is an oddball choice.

How about this posted on BaT today. 1955 Studebaker President Speedster. [bringatrailer.com]

I know that it doesn't have 4 seats, but can't we make an exception this one time? 1930 Bentley Speed Six Gurney Nutting Coupe

Any Aston Martin DB9

2002 Aston Martin DB7 Vantage Zagato

1970-73 Maserati Ghibli SS

1953 Hudson Hornet

1947 Packard Super Eight

The first of many submissions. 1936 Cadillac 452E Fleetwood Aerodynamic Coupe

A friend of mine has an early 4th generation mustang and despite being only 6'1" there is nowhere in the car that I am comfortable. Even with the seats in the rear most position I don't have enough leg room.

Not only was it the budget drag car, but it was downright cool. The 1969 American Motors/Hurst SC/Rambler, preferably in the B paint scheme.

How can you argue with a road legal Jaguar D-Type? I nominate the 1957 Jaguar XK-SS

I'm a big fan of the e39 Touring. With a wide variety of models to choose from, there is an engine for everyone. My choice would be the 530d.

For the ground clearance and intimidation, I nominate a classic Unimog.

Actually the more correct spelling is Honour. Honor is an alternate spelling. They both are technically correct, but since Honour predates Honor by 150 years it is the spelling I use.

I think the definition of tiny works with the Focus. It isn't the smallest car, but I wouldn't buy a car much smaller. I like the polestar, but it is a concept, not a production car, and it was already suggested.

Will people please stop saying stupid things like the "heaviest thing ever." The heaviest thing ever would be a planetary body somewhere out there that we may not even know of yet. The Saturn V is not even the heaviest man made object. The Great Pyramid of Giza weighs somewhere around 6,000,000 tons or 12 billion lbs.

Thats nothing. Try 8,873,000 lbs. of thrust from three stages and total weight around 6,699,000 lbs. It is inaccurate to compare thrust to any kind of power, hp or otherwise. That is to say many measurements and calculations must be performed to determine the power of a jet or rocket engine. There is no straight…

The answers seem to have gotten away from the point of the question. TINY car and a big engine. I'll leave this here to get everyone back on track.

And the Ford RS200 Evolution
