I would walk away unless it's like new and includes a trailer. Or negotiate more. Not horrible but not great.
The bigger motors are often good for 1,000 hrs but I don't know about the 787cc, but maybe priced a bit high.
Area makes a big difference there.
I have a 07 gti 130 (hp) with 120 hours on it, looks and runs like new, with a like new trailer that I'm probably only going to get 3-4k for. (paid $4800 4 years ago with 70 hrs and a completely rebuilt and painted trailer)
