Hi, I'm looking to buy an A6 Avant in the next couple of months and I've started researching the various models. I'm coming from a Mk4 Golf V6 4motion which i love (but too small for the growing family!) so I'm looking to get something with quattro and a reasonable amount of bottom end power. I'm going to be spending between £5-6k so I guess will be looking at a higher mileage model. So far I've narrowed it down to the 2.8 V6 quattro (seem to be more of these around), 2.5 TDI quattro (seem to go for a bit more money) and if one comes up at the right price, the 2.7T quattro. Any opinions on these models? or any others I should be looking at? Any advice appreciated. Cheers.
