Hello mate
First let me say welcome to the board..
Second.. err why do you want to buy a racing DC5 but you tend not to track it that much. :roll:
I wouldnt bother if I was you and just buy the normal one, you are going to spend a lot of money getting it road friendly and it will be a hasstle to pass the SVA, you will probably end up spending 15K, so why not just buy a use DC5 and if you wish to track it, so be it..
basically it comes with nothing apart from a seat, by the time you add another front seat and rears (if thats your plan) you will still have no sound proofing, (that is going to be very loud on the road), no speakers or even any speaker brackets, wouldn't suprise me if there wasnt even any wires ran for the stereo, afteral its a trackcar... !!!
So I would really think again if I was you.. if you were thinking about 70% on track and 30% on the road then fine, buy it.. but it sounds like you are going to be 20% on track..
Just think about it carefully mate otherwise you will be spending a lot more money than you think and it will still be very noisy in the cabin on the road..
