First off JaimeZX made some good points -- I had been saving for my Z for a *while* and it sure felt good (and still does) to get it.
If you want it that badly and have some money saved up, find a good TT you want and get a loan. There are ways of finding a place stupid enough to give you one (hey if they'll give one to me, they'll give one to anybody). Sure you'll be working your tail off to pay for maintenance let alone the car payment, but dammit it's worth every cent.
