Any Aston Martin or Alfa Romeo is doomed to complete destruction.

whether the reasons given for who did the wrecking are true or not:

There's an old English movie called "Genevieve", 1953, in which two friends who are real rivals as well race their antique cars from Brighton to London. (British traditional road race, apparently.) "Genevieve" is the name of one of the cars. It's a charming low-key typical British comedy. Kay Kendall, that beautiful lanky redheaded comedienne is in it in one of her first roles. As best as I can remember, no cars were injured in the shooting of the movie.

But the limo in Desperately Seeking Susan comes to mind.

Dave Whiteman (Richard Dreyfuss) in "Down & Out in Beverly Hills"
George Webber (Dudley Moore) in "10"

that there are a finite # of these classsic cars left and they are being ruined for cheap laughs

as I said this was years ago (can't find the Siskel and Ebert clip) so how many more of these classic cars have been ruined since then?

Classic Car Rule
Whenever a beautiful classic car—usually the prized possession of an unsympathetic father—is
introduced at the beginning of a film, that car will be wrecked by the end of it. (See RISKY
BUSINESS, FERRIS BUELLER'S DAY OFF, COUPE DE VILLE, etc.)

Extra credit if the car drives into the pool, the large splashes created cause much stir among the heretofore idyllic poolside denizens.
