Our mates up in preston will feed you with the old "ah sorry that ones sold, but we can get you one just like that in 3 months for £xxx, just leave us a grand deposit and then next ones yours"
Then funnily enough all the ones that are "sold" seem to keep appearing over and over again year after year.
Tried the same with me 18 months ago, little coughing dude assumed everyone looking for a NSR was a bit wet behind the ears. Should have heard some of the old pony he was coming out with. i humoured him before leaving sharpish. Waste of a couple of hours ? not really, could have been an expensive mistake and i pity the unwary who are not so local.
As has been said, they seem to be made to order from the tons of parts they have upstairs from years ago. incorrect parts, all painted by dream machine etc etc.
Be patient, you will find alot better for your money if you keep your eyes open,
