From what i have heard CUP turnini's rub slightly on a 182, especially if lowered. dont know how true this is though.
As said the 15'' OZ F1's are ideal wheels and cheaper.
If you look in the book it should have boxes ticked of whats been replaced.
usually its just oil/filters/plugs. but i believe its a common fault for the auxilary belt to snap before the reccomended change time (60k) so some people change these for piece of mind.
Also you could try ringing...
I am looking to get an exhaust but was a bit put off by the look of most of the tailpipes.
I prefer ones that look like the standard exhaust rather than slash or jap-style.
