well for the money you spend on buying an GSR you could used it on buying an GSR tranny and motor, thats what i would do. plus you'll be saving a lot of money, so why not just keep the car and maybe sell your motor to get some extra $$$. since you say it only has 80K on it.or sell the car and hope you at least get $4500 but then you'll still need more to buy an good condition GSR.
