The thing is there is kit to consider on a 12 year old vehicle with 20 miles.
Set of tyres, wiper blades, ac splitter valve as seat seal will have perished. expect some of the other rubber bits to have gone off. electrics may play up on dry joints. Waxoyl the underneath etc, Mice damage to sound proofing, bonnet lining, looms

Could be 2000 to get it on road plus a C service to replace fluids with the diff oil smelling enough to be fatal at 100m! so Steve's about right 20k + / -Sunroof seals, Lovely for a V8.
