Advisories at the latest test: suspension pipe damaged but not to excess all suspension pipes corroded; nearside rear tyre slightly damaged/cracking or perishing; offside rear tyre slightly damaged/cracking or perishing.
Mileage at that test: 51,526 miles. The advert says 50,000 miles, fewer than the MOT record, so ask the dealer which is right.
