4.Porsche 911 Turbo (996, aka 2001-2004) –$30k+
If you are searching for a Ferrari-besting performance in a car, I advise you to stop looking because we have found your car.
As one of the supercars you can buy for under $50k, the Porsche 911 Turbo is priced at $30k+.
The 2001-2004 models are exactly what are you looking for, because this generation of car is famous to the cognoscenti as the 996 is a bit off in terms of pricing.
The prices of newer 997 Turbo cars haven’t fallen enough yet, while the older 930 has already attained legendary status, due to both its reputation as a widow maker, and the affinity of nostalgic Porsche enthusiasts for air cooled engines (which went extinct when the 996 came to pass).
