Hi James, thanks for the reply.
I'm considering it. I do a lot of miles each year, roughly 32k. So although I knew that the car wouldn't be super economical, I based my numbers on the information I had at the time. Likewise, the value of the car at the end is surely now less than indicated.
I'm on my third Audi and love the cars and the brand so don't necessarily want to step away from that.
