any tips on which extras a dealer will most willingly add to a pre-reg "2nd hand car" car? my dad managed to negotiate DAB radio, front parking sensors and the upgrade to the higher spec sat-nav on his 12-plate C6, but was that only 'cos they were desperate to get the C6'd off the forecourts? The car I'm looking at is a nearly new C7, but I was just wondering which types of extras dealers CAN wangle and which will just p!ss them off? (e.g. "I'll take that car if you fit a sunroof / quattro") There are a few features I either need them to include or I'll retro-fit and I'm not keen to fit something to a car with <500miles on the clock! I've found a car that has all the main things that I'm after, except a removable towbar and DAB, I'm sure the DAB is a no-brainer, not sure if they'll do the towbar, but are there any other "nice to haves" that I can get the dealer to throw in without too much hesitation? e.g. I would like to have the rear privacy glass and sunblinds for the kids in the back. I guess really what I want is a Black Edition, but can't find one Rear entertainment kit would be nice too! I'll have another look later, but the rest of the spec is pretty much what I'm after.
