My friend is fixing his fixing his Z and tZ fever quoted him 2.3k for timing belt and some leaks....guy said he thinks its leaking from gasket valve????????? and some radiator fluid leaking from somewhere, he didnt know were, he thinks its leaking from the cap???? somewhere on the bottom of the car. this and their gonna put spark plugs and do a "tune up". Maybe im crazy and i dont know enough about what their doing, but 2300 seems like a crap load of money for that work. They are pulling the motor out tho, wich u pretty much have to do for anything on the Z
