Hi, I've been looking for an A6 avant now as a replacement family car to our 52 plate A4 1.9 TDI. I had originally been looking at a 2.5 TDI 180 Quattro around a 51 plate & spending around £4500-£5000 but the misses is not really into the shape & doesn't really like it that much. She keeps saying she has seen nicer ones & I explained that it's probably the newer C6 shape she is referring too. Showed her some pics & I was correct it is the C6 she likes. I have since found a 56 plate 2.0TDI A6 Avant SE for £6750. It's a little more than we wanted to spend but can't help thinking what a much nicer looking car the newer shape C6 is. It's silver with 18" RS6 alloys, high mileage for the year at 122k but full Audi service history. The only thing I was really into getting a nice 180bhp Quattro & remapping it to 210bhp but now I've started looking at the C6 I'm kinda thinking it's nicer too. I will have to sacrifice some power though & no Quattro..........................I'm in a bit of a dilemma now! Is the C6 a much better car to have overall? It's probably a problem some of you may have faced, an older more powerful car or a newer less powerful more sensible car.
