I sold my '75 Targa in 2016 after rebuilding it almost twice -

I feel my listing and the process proceeded very well and reviewing the listing and comments would be informative.
I provided many pictures taken late afternoon with HDR (high dynamic range) mode on as cellphone. I provided them in an organized and labeled manner. I provided a whole bunch of lists of work done and the story behind the car. Their staff wrote up the description (they used a consistent 'formula', which helps make the listings comparable). Primarily they describe the car objectively using picture and provided evidence. I had three pages of information (in the Gallery) which really helped to beef up the information that was written into the listing by BaT.
The buyer pays a percentage and pays transport. The seller does some valuable work promoting during commenting, pays a smaller listing fee and makes the vehicle available for transport.
In the end my Targa sold for much more than I expected. $36,500

To a German buyer.

Early on and before many comments the bids surpassed the reserve I had considered. The comments were primarily positive - which helped a lot. During the week the auction was active I made a video to further enhance the listing - I upped the game.
The German buyer was required to change to H4 headlights, replace the chipped windshield, Europeanized the rear bumper etc and two years later I heard from a new owner in Germany.
Good luck Angela -
