Have you managed to haggle a discount? If the dealer you're visiting doesn't budge much on price I'd try orangewheels.co.uk, they put me in touch with a nissan garage and I've been dealing with a guy called Chris there who has been very helpful. The orangewheels garage went £1250 lower than my local garage would go for the 40th anniversary. They were having problems finding one now though so it might be a bit difficult to get one through them.
Yes, I negotiated the price down by 10% and got free mats thrown in - so a little cheaper than orangewheels, and from my local main dealer. I went for the supaguard treatment too - I had it on my now-being-sold Toyota Celica I bought new 8 years ago and it's a fantastic product. My Celica today looks just as good as it did when I drove it off the forecourt 8 years ago. The interior still has a nice sheen and the exterior looks beautifully waxed after just a simple wash. For around £300, I can't recommend supaguard enough.
Hoping to pick my new baby up on Saturday, just before we drive to visit family in Surrey. I can just see the look on my 10 year old nephew's face now. Will probably look something like the look on my face!!!
