Cheers Exonian for the extra info, thought they looked similar anyway around the wheels, appreciate the clarification.
Just got back from seeing one in Oldham at A1 Ortos, on the off chance anyone is interested in it, forget it unless you want a cracked sunroof surround, shabby interior with pock marks on the seat bolsters and scratches on the center console and most wheels needed a refurb! Said they'd sort all those items when raised but 25k on the clock and wanting £28K+; not a chance; expect that's why it's been there nearly a month now whilst I've been looking.
Got taken for a little spin in it, no knocks or anything but on the one occasion it was pushed hard there was a loud whoosh of air from the bonnet I didn't get the other day when I drove the nearly new one. Might be nothing but was out of place when flooring it to 50mph. Didn't drive it myself as after seeing the condition and the fact they'd want £2k paying if anything happened on the test drive before I could leave the premises I declined and said they could drive me!
Tried all the settings though and found DCC on or off negligable at best on all settings so think I'm comfortable with passing on DCC now.
Good point re the Belvedere's tyre choice, Bridgestone's are harsh and noisy and would make a difference, forgot about that. I'll be happy enough adding some 19's, either Reifnitz or Pretoria's to make it like a standard car's options, the rest is all good!
This will likely be my long term (5yr+) car so I want it to be spot on now and if I can add bits aftermarket then that's fine, the one thing that would be difficult would have been DCC which I feel I just don't need now.
