That is a very clean car, and a U code to boot and LOTs of cool options. I would check out if it is a true U code, numbers matching, with all thoses option originally. He say's he has the buildsheet for it.
Here in the states, a would think if it is a true U code and those options, it would be in the $60,000 to $75,000 range.
I hope its real and that you get it.
