I bought a 2000 (X) reg and to be fair don't mind repairing things when they go wrong - its more fun than watching telly ne ways and its a good excuse for having to buy nice new shiny i really must have it tools!
So far nothing what I would call major mechanical - changed oil and filter, fuel filter, brake fluid, crankcase breather, gearbox oil and IRD oil, topped up rear diff, rear brake shoes, lost all power steering fluid over asda car park without warning, tightened clips on pipes n cured that, antifreeze change... errr think thats it. So just general service stuff in 2 years - oh and i get 40 mpg on average - mainly decent runs for that though!
One word of advice if you do get one - be prepared for it to go wrong but there are loads of happy hippos out there.
I also changed the under engine tray bolts and screws etc for new and greased em well - makes taking the bloody thing off easier.
