mines now got 7k on it and im only half way down the original tyres, so no real worries there, you will love it, take it steady and get used to it, try and get it on a track(where its a bit safer) so you can learn its limits , then you will know what you can do and what you cant, it goes round corners like you wont believe and is quick enough to worry alot of other cars, dont listen to the negative comments on here (i cant really understand why people do that,especially as you havnt even got the car yet), i can honestly say i never regret buying the cup, and i did try a brand new 172 and a brand new 182, but i much prefered the cup, for looks and for go, and the fact that i couldnt justify spending nearly £4000 more on the 172/182 and all i would of got for this is toys that i never use.
enjoy and dont listen to the negatives, and if you do have a minor problem, take it back and get it sorted under warranty.
