Buying advice please

[Rural13]

Hi, looking to buy a 2007 A6 Avant 2.7 TDI S line, 210,000m, plenty of service history and seems to have been well looked after, gearbox oil changed at 90+140k, looking to pay around £1k. Anything that I should be aware off, it's the original internal chain, is this an issue, seller says everything is fine and seems a genuine chap. Many thanks Colin
