Just a quick one. I'm thinking of getting a diesel A6 and wanted peoples advice on which engines are best and things to look out for. I'll be looking to get a C5 and I don't have much money to spend around £2500 is my limit really. I know I'm looking at cars well over the 100k mark and I'm ok with that. I owned a 2000 A4 about 3 years ago (2.8 Quattro petrol) and it was the best car I've owned I honestly wish I'd never sold it. But it was thirsty so had to go. I currently have a Honda Accord Type-R and again it's fairly thirsty and insurance is high and I've got another baby on the way so want something sensible that's going to give me fairly good mpg's. Just looking for opinions and advice etc. Any input welcome thanks.
