Had a sneaky look at these myself, a mate of mine had one and it was phenominal.
Don't expect running costs to be cheap though as it's a supercar, there's a few on the Market between £20k-£25k, I would be a bit wary but you can get good independant warranties for around £400 a year plus you can get the Porsche 121 point independant check for around £150 I think.
