Do you really not know the answer to that? There are a number of factors. Those 3 cars are about as close to a race car as you can get. I'm sure you know what it takes to upkeep a race car and having an exotic like the 3 I mentioned also requires a lot except for maybe the Carrera GT. The clutch design on it is revolutionary and does not even need to be looked at until 300000 miles as well as the engine tune up is not scheduled for 15K miles.
If you have one of those cars in your garage, you are not driving it every day and will put even less miles on them as you would a Viper. Also, if you have that kind of coin laying around, having to pay for all the required maintenance/tune ups is the least of your concerns.
Don't get me wrong bro, I LOVE my GTS and will probably have it 30 years from now. BUT, if you have ever really looked over an exotic car like the 3 I mentioned, I mean, spent an hour really becoming familiar with the car and all the attention to detail, it would truly blow your mind! I got to see the Lambo up on a lift and all I could do was just keep picking my mouth up off the ground!!
