I went thru 5 VINs before I got my car (LR, RWD, delivery in Los Angeles, Marina Del Rey)
1st was 401xx rejected on July 14 due to misaligned panels, scratches on driver door, hood, dings, etc.
2nd was 566xx - MDR delivery center called Aug, 7, the night before delivery to cancel, last batch of cars had paint issues
3rd was 401xx - called the day before, Aug. 20, car passed QC, good to go, got there the following day, the car wash/detailing guy found a scratch on the driver side door, that no one noticed before, tried to touch it up, made it worse, car has to go to body shop for repaint, will take 1-2 weeks. Since I'm planning to keep the car a while, and repainted body panel will affect resale, I declined to take it.
At this point (Aug. 21) I decided black color may not be the best idea, so I switched to silver. Made it clear that I wanted a new car, not one that had been reworked/repainted.
4th was 373xx - delivery scheduled for Aug. 28, assured up and down it was a new built car, insisted on seeing the Monroney sticker, turns out it was built in June, so it's been around 2 months, obviously something's up.
5th was 613xx - took delivery on Sep. 2 - (silver) some very minor paint issues, and misaligned panels, but very minor. Took the car, best one I ever owned. Friend of mine who used to work at Porsche and Ferrari dealership was with me, took it for a spin, he was impressed, he said he now understands why I waited for it so long, and why I put up with all the issues.
Car is great, buying experience was not.
But in the end, it was worth it.
