Have you spoken with Peter the owner? Or has he even returned any email or texts? I tried asking questions and all I got was a link to some 5 year old photos. It took three attempts to get that to work. The first two attempts all I got was a blank page with no link. I had to do some sleuth work with a plain text ISP interface to find the URL address of the shared drive.
I did not get a good feeling as the car shows issues in those five year old photos. I feel if you want to sell a vehicle you show it as it is TODAY! You should be up front and honest about what is good and what needs attention, now or in the near future. There are better cars for sale from people who will respond to your questions with intelligent answers. YMMV
