haha :Bang:Re: Maintenance - To me maintenance means things like; fluids, brake pads, tyres, filters. It doesn't mean upgrading turbo's, replacing exhaust systems, aftermarket computers, bodykits etc.
I have an R33 GTS-t, every 6,000km I put new fluids in it and replace some filters. No different to what i'd be doing if I had a GTR. So why does 'maintenance' cost more? Now if I wanted to spend money on upgrades the GTR is going to cost more, partly because its a "GTR" and shops charge more and partly because you need twice the parts.
So personally i'd be throwing the "maintenance is more expensive on a GTR so get a GTT" theory out the window and replace it with "if I want more performance out of a GTR it's going to cost more than a GTT".
The R33 GTR looks tough but it's also starting to get very old. I'd be getting the latest model I could find, where as the GTT is fresh and newer and (at the moment) rare but that always changes as soon as you buy the car. If you plan on doing trackdays, drags, etc then get a GTR, if you just want a daily driver and some cruising get a GTT.
