So far mine has had a replacment gearbox but that was probably due to the last owner driving it like a c**t?! The gearboxes are in general quite week though. Ive had the circlip go on my dif which was about a £100 fix including the towing, apart from that in had it about a year and all else its needed are normal stuff, like rear discs + bearings + pads, battery, and the all important 72k/5 year service which includes the cam and aux belt change.
