One of the great classic British sports cars, the Jensen Interceptor is a fantastic example of the big late 60's early 70's GT car. A must have at the time owned by lots of celebs and still stunning to look at.
Mini Cooper 1275GT. The design classic, still fantastic to drive and likely outhandle a lot of so-called current super-minis. First car with front wheel drive and an icon of the 60's. Fond memories of being driven to school with 3 other kids in one of these. Forget the current BMW version, they have destroyed the soul of it, look instead at the Fiat 500.
BMW M6 from the 80's. One of the best cars BMW have ever made. Had a chance to buy a mint low mileage one off a friend in California once. Should've done it... Other than the 7 Series from the late 90's its all been downhill on the design front from the boys in Bavaria since.
