I've recently changed my wheels, springs and lights on an e85 3.0i. Can't really see any point in keeping the old bits.
I can't see myself ever returning the car to it's original spec. If it was worth more then maybe, but for a car that's only worth about 5/6 grand the parts will just be taking up room in the garage for no real reason, plus then i'd have to sell the new wheels etc etc.
Just gonna shift them i think.
