I did a very similar deal with Orange Wheels online. The local dealers to me are Glyn Hopkin, who wouldnt budge on the price of a new car at all and who tried to sell me a deisel car with 10k mile on it for the same price as a new car (more or less) and Toomey Nissan at Basildon, who ignored me when I went in and asked for a car. They said sorry dont get many of those in stock and went back to his private phone call....So I walked out.
I'll get my servicing there, but only because I have to, to keep my warranty.
Ouch!
