Think of a Ferrari with 30-40k miles. Same service costs, clutch life for the F1 is 10k miles max. Cost is $5k. Electrical issues galore. I mean the check engine light comes on until the car warms up!
I would say most owners spend $10k a year on maintaining these cars.
Save your penny and buy a nice 996 or early 997 and be happy.
Or go buy the much better looking Gran Turismo and get a good warranty!
