Richard did make a good point. People are all up about services to keep it at it's prime and forget that the actual visual appeal of a car makes a huge difference. Waxing a car every month or so will keep the paint looking like new and it really should be considered general maintenance.
Wash every weekend and a detail every 3. I do that to my GTR (when i have it =( ) and it keeps the paint looking incredible. It doesn't take very long either. I have got a full meguairs kit ready to go when i get the call.
