Be carefull, lots of bodyshops will no longer take r'overs, and if they do they will only "take" the car once all the parts are instock, this creates major issues with courtesy cars as most insurers will give you a loan car in a no fault accident but this is from the repairing bodyshop, if they wont take the car for 3 weeks then you don't get a loan car.
Some parts are really hard to come by, mechanical stuff is fine, body panels are different, and some insurers will only fit "Genuine" panels which would write off a rover with a split rear bumper.
On the otherhand there are some superb CAT "D" R'overs out there that have had minor bumps and been written off by the insurers, a mate bought a fully documented 75 CDTi Connousour (sp) tourer on an 04 plate with 36k and full history, it needed a fr bumper, o/s headlamp o/s wing and a bonnet and he paid £1800 from salvage auction, £350 at scrapy's later and £250 paint shop she is a minter! looks £7500 all day long!
