So that got us thinking: Why don’t we compile a list of the great sports cars from the last couple of decades that had their 15 minutes of fame, but remain great automobiles? The cars were equally different as well, with the E39 M5 being one of the best four-door sports cars of its era. Perhaps it was such a great car that not even Mazda itself could replicate the same success. However, car enthusiasts know it as one of the great “sleeper” performance cars. I’ve seen good ones go for anywhere from $20,000 to $60,000 on platforms like Bring a Trailer and Cars and Bids.
