This thread is taking a twist away from the for sale ad, but I guess it keeps it at the top and visible, plus maybe we can just convince Alex not to sell!
From someone who has bee down the road of race cars here's my take;
I started with a semi-street car (Ultima CanAm) and soon found when you push hard stuff breaks, so you get a trailer to not be stranded at the track. Then you tell yourself now I have the trailer I can modify the car to be more track/race ready.. it's a slippery slope and before you know it you have a race only car, that is no fun on street! A few iterations and ~$45K later my race car is an open wheel Formula car and it is literally the most fun you can have with your clothes on! Prototype and formula cars with outstanding performance can be had for a fraction of the Porsche GT3 RS entry price, the only disadvantage of an open wheel car is restricted open track day events, but P1 cars are faster now anyway.
I keep toying with the idea of selling the GT5 or GT40 and getting a modern sports car, but I just know in my heart I'd be bitterly disappointed after the initial rush of having a new car wore off.
