If I weren't so bias toward Buicks I would say 67 Corvette, but I really like the 1st generation Rivieras Bob H.
GSX's of course but I also like the 1968 Dodge Coronet R/T's and 71 'cudas. I have a soft spot for 67-70 Shelbys too and early Rivs.
In my opinion one of the nicest cars ever made and I've seen it in the flesh. Yes it's a concept, I wish they'd made it production.
My choices are in this order; 1) 1936-39 Mercedes Benz 540K 2) 1938 Buick Century/Roadmaster 3) 1946-48 Buick Super/Roadmaster 4) 1959 Buick Invicta/Electra 5)1962 Olds Starfire
I know what it is but Im not going to tell......I'll give you a hint. The country of origin is renowned for over engineering thier cars.
1961 Buick Invicta 1966-67 Riviera 1969 Buick GS convertible. .. Not necessarily in that order! Buick Eric / Oregon
I too like the first generation Rivieras. The '63 Ford Galaxie fastback was nice, and (believe it or not) I liked the '58 Plymouth Sport Fury hardtop. I loved my pair of '62 Chrysler 300 2 dr hardtops. As to Buicks - I liked the '55 and '59 and '60. In fairness, the styling just appeals to me. From the classical standpoint, the '61 was probably more beautiful. I also liked the '56 Ford Crown Victoria Sun Valley. It was gorgeous, but in reality it was an impractical POS. '63 Corvette Coupe would be on my "most beautiful" list.
