6: BMW 850CSI
What was once considered a supercar the BMW 850CSI has aged like fine wine. The car has also depreciated in value and one of the reasons for this is that the car has a lot of issues with its electrical. But if you are willing to put up with constant maintenance, the 850CSI is a car that will leave a smile on your face every time you drive it (via Motor Trend).
Prices for the 850CSI have drastically decreased in the last decade, and you can find higher mileage models for even less. But the car had a wonderful amount of power and luxury for the price. The 850CSI is by far one of the best used sports cars you can get for the money and one that will leave you smiling.
