can we get back on topic please? this is not a GTSt vs GTR thread.
as previously posted I've had no engine problems. however, maybe we see a lot of maint issues with GTRs because not many mechanics around really know them. i mean REALLY know them. i've been to a couple of the supposed better/more established ones in sydney and while they can build engines and diagnose stuffed afm etc (so can i), if i go to them with some little quirky problem they don't know enough about the car to fix it quickly and just go chasing the usual suspects. then i get the car back with a bill saying it's fine when i know damn well it's not. in many cases a thorough read of the manual the night before makes me better informed than they are, and this seems to be the case particularly where electrics are concerned. and there are quite a few of them of the GTR.
i used to have a starion that was serviced by Kevin Bartlett's shop, in 90% of cases i'd say 'it's doing blah' and he'd say 'that's because...' and it really was. and although it is a less advanced car than the GTR it was pretty trick for its time.
admittedly i've been stuffing with cars for 20 years but i still hope to find a professional out there who knows the GTR like KB knew the starion.
