I am having a new or shall I say used TT engine put in my car. The shop that is doing the work has had my car for going on 2 months and just recently told me that I need a new clutch. I have payed them $3,000 for the engine and they want another $G for the labor. Is this the normal time that it would take to get my car back on the road, or are they trying to take advantage of me because I'm young?
