Hi Chris
I bought my TT SE new in July from GS Gedge in sussex they gave me £3,000 trade in for my bike that another dealer offered me £2500 for so there may have been a sweetener there, I paid £500 on top of retail but got heated seats, grips, top box, frnt fender extender, paint protect, tank bag, a £350 Navigator jacket, two years free servicing, and 2 years interest free on a couple of grand.
I was happy with the deal, I'm sure there have been better ones but it suited me, hope this helps you get a good deal yourself.
Roger
