The chargers on the G60 need servicing every 60k on standard pulley. Its a little cheaper if sticking to standard, but with stage 4 its down to a 30k recommend, and 500 notes for rebuilds every couple of years dependant on how often you drive it. Obviously if its gonna be a daily, go for the 16v (apparently the 1.8 is better than the 2.0). I'm definately gonna get one early next year, and have been looking. Signed up to corrado_net.co.uk, and asked a few questions and had a look on there. My missus will be driving again in February so will be doing less milage, so I'm going for the VR. There are tons of em about too and dont fetch much more than the valvers. Again though, unless you spend a fortune, you wont see much more than about 220 bhp regardless of which one you buy.
