I would say 7K is absolute max for a genuine Super Rocket with original engine, frame, registration and documentation to prove, running well and in virtually mint or original condition. Any of these criteria not met would reduce the value considerably. Personally, I wouldn't be too bothered about the reg. no. as long as it had three no's and three letters or four numbers and two letters, but I would expect the price to reflect this. Super Rockets are starting to fetch good money but, from what you say, you should be able to find a Super Rocket of equal merit for about £4500 - £5500 (in my opion). What do others think?
