In the end I purchased via. Drive the Deal, I had 4 Audi dealerships all vying for my trade at the same time, was getting to be a bit of a headache with 'e-mail tennis' in works time!
Manchester couldn't get anywhere near the broker price, £100 out a month lol, still rang me saying 'what do you think of our price'?!!
Bolton - still £30 out a month after loads of e-mails, they threw in GAP stating it was worth £700, I said I can get GAP return to invoice for years 2-4 inclusive for just over £150 so forget it.
Doncaster (only got involved with them due to a work colleague recommendation) - similar to Bolton within a few pence minus the GAP.
Huddersfield (again work recommendation) - reckoned they could've matched the quote within a 'few quid' whatever that means(?) after I had signed up with DtD.
So, I will be travelling a good few miles to get mine, but so what it's a day trip out to pick up what I hope is a fabulous piece of kit!
