What went wrong on yours? I dont really understand how a 200 could really cost very much unless massive components broke on you?

My family have had loads of rover's and all have been excellent reliability wise and have cost near on nothing to maintain.
Here's a list (retrieved from my thread on the MG Rover forum):
I really enjoy getting into the car and driving it but it has cost me a lot of money over the last 18 months since purchased - too much really IMO for a car that's five years old (2002/52) and has done 57,000 miles.
Costs so far (excluding insurance, fuel, tax and depreciation):
- 60k service last year (with new discs and pads, including MOT) £750
- 2 new tyres last year £200
- New exhaust (mid and rear) £250
- New fuel filter with diagnostics (running poorly) £120
- New headgasket and cambelt £800
- Another two new tyres £200
- 75k service (with new discs and pads and a new passenger headlight) £950
- MOT £50
- New windscreen wipers and headlight bulbs: £30
Total £3,350
Faults:
- Boot doesn't shut properly - fixed by removing and regreasing mechanism
- Rear and front washer jets not working - both fixed in the 75k service
- Glovebox has fallen off (not fixed yet)
- Sunroof leaks (not fixed yet)
- Trim has fallen off the door handles on the front doors (not yet replaced)
- Badges have delaminated
- Still uses coolant and can't find out why
All of this work was done at Barretts of Canterbury
At my parent's house I had the inlet manifold gasket replaced by their local (ex) Rover dealer who they trust to fix the coolant leak. The oil filter was loose and the Inlet Manifold hadn't been replaced previously (which it should have been at the time of the Headgasket replacement) so I lost faith in Barretts. In all fairness I didn't help myself being such a mug and going back to the same super expensive dealer but it was a long list of faults.
The Astra Coupe has turned out to be a nightmare too
To the OP - it was a great fun car though and I don't want this to put you off too much. Just go into it with your eyes open - the guys at the MG Rover forum are very helpful too.
