My family owns a 1970 model XJ6 that is very similar to that albeit a 4 door, needs restoring though which I'm hoping to do in the next few months.
How about one for each decade starting with the 50's 50's the 1959 Chevy El Camino 60's the 1965 Buick Riviera 70's the 1976 Pontiac Firebird 80's the 1984 Lamborghini Countach 90's the 1991 Dodge Stealth 00's the 2006 Pontiac Grand Prix 10's I don't know
I recently started loving the Dodge Challenger, I just like how it's reminiscent of cars from the 60s/70s.
Ferrari 458 Jaguar E Type Porsche 996 911( sorry if people think this isn't that good looking, it's just my opinion). VW Polo R WRC Alfa Stradale McLaren P1 (only in blue, though. The yellow is kind of ugly.)
