No, unfortunately they parked somewhere away from my block. Playing it back in my head, it was quite an elaborate scheme and there were many things he did that made me gain his trust:
-He came with his girlfriend and they did not look shady aesthetically
-He visually inspected the bike for a while and had a conversation with his girlfriend on her opinion about it
-He started the bike and negotiated the price instead of offering my full asking
-He was willing to wait for the cash to come back
-He was able to answer all my questions about his work, his bikes, his brother, his locations without a single "ummm" or pause/hesitation
-He did not push to offer me his license or anything to get the test ride
-He didn't even have any gear besides his helmet and gloves, it was freezing out
So what I'm thinking happened is that his girlfriend probably went back to their truck and set up the ramp so that he could ride the bike into the truck or van a few blocks away and drive away undetected from the scene. Kind of like Ryan Gosling in that movie "The Place Beyond the Pines".
Anyway, I will definitely keep this thread updated with any news
