I sold wheels to someone once and agreed to meet half way. I got to the half way point and they were only way half way from where they had left. I got back on the road and kept driving, gave them a new meeting place closer to where they were. I honestly started to think I was getting trolled on that one. Some guy on vwvortex was buying them from me, but he was having this girl come pick them. I started to think I was being fucked with and I'd be driving back with my wheels.
It worked perfectly when I sold my mk6 tails though. He drove south, I drove north, and we were literally pulling into the parking lot together. It could not have been timed better.
