4: Cadillac CTS-V
The original CTS-V was a breath of fresh air for the brand as it introduced Corvette power to an otherwise sedate car. The CTS-V was a hot seller for GM and managed to stay on the market for a long time. The performance of the CTS-V is still competitive today and there are many upgrades for this car (via Motor Trend).
The CTS-V model was offered in several different styles over the years but the original is still the most fun to drive. For the price you just can’t go wrong with the exceptional build quality and off-the-line performance. The CTS-V is by far one of the most exceptional sports cars in quite a while.
