It was built before April 2005, because that's when all Rover production stopped. It might even have been built in 2004. (Check the seatbelt tags.) There could be engine and turbo damage from oil contaminated by condensation. It will need a new battery. The exhaust system might be rotten fro condensation. The brake discs may have rusted and need replacing. The tyres may have flatspotted. But it's doubtful you will find another 75 2.0CDTI for this money with so few miles under its wheels.
