hello...im looking to buy a my06 from second owner. it has the chip and an aftermarket cold air intake. the first owner installed these items and drove the car until one month ago. the second owner has had the car for exactly one month and now wants to sell it. what do you all think about this situation. what should i look out for to make sure the engine has not been compromised etc. any advice will be greatly appreciated.
thanks
