So lets stick to RUNNING costs and not mods. The 2 are miles apart.
eg my last service, oil $50, filter $20 but will last 4 oil changes, labour nothing.
WTF, the same as my 2 GTS25t's and V8 Soarer.
Tyres are due soon, $140 each with 90% rubber for Dunlop 9000SP 275 35 18 from Europe, so $20 more each than the GTS25t track car.
Fuel is costing about $20 a week more but hell, I'm enjoying it right now and driving off to a few dive sites.
