The problem I found when trying to price it was that there wasn't that many around. The only others I found where 180,000miles + pretty average condition and still selling for about £1750. Then you look at the A4 2.5 Avants and they are all advertised for around the £4k mark, but then an engine like this is probably more suitable for an estate rather than a saloon, plus there's more demand for an estate with a big diesel engine. I am still suprised there has been little interest!
in answer to others questions yes, it is silver and a diesel, I've only been driving it for a month or so since getting back ont he road and only selling as I bought a new project Audi S3, but I have to say the A4 v6 engine is a pleasure, especially on the motorways and A roads, to drive. It's a little like a tank around town, but let it loose a little and it goes as well as any other car i've driven. I've not driven a chipped version, but reckon it would benefit vastly from it but a little reluctant to do that as the car is still stock engine wise and would rather sell it like that than limit myself to who would buy it. Then again, it may need chipping to get it sold, and I've been quote £200 to get it chipped so it may be worth while.
I've just re advertised it in the auto trader for 3 weeks and put it back on piston heads so I'll see what happens. I'm pretty sure though that it is the right car for someone just need them to want to buy one.
