It certainly meets all criteria for past collectible BMWs:
*Two Doors
*Very Expensive when new
*Produced in limited numbers
*Very difficult for dealers to sell when new
Nothing explains why currently the Alpina version (automatic) is eclipsing the stick-shift in value—other than rich people can’t be bothered shifting? Or it belies the true nature of the car as a boulevard-cruiser for profiling rather than actual spirited driving?
No question of it being beautiful and the rapid increase in value of the 507 over the past decade certainly doesn’t hurt it, either!
