plan on giving it a thourough test drive and wanted some advice and what to look and listen for while checking this car out
Well, if it's 'built' it ought to be able to take a little pounding on that 'test drive'. I'd drop the hammer and let it rip - put it through some grueling miles accelerating, shifting, braking, cornering and driving in general. A sissy spin won't tell you siht. Put it to the wood, work it, and let it tell you.
