Most panel gap issues or trim gap issues can be fixed without too much effort. Also keep in mind that gaps around the car come in varying widths for certain reasons and functionality. I think there are too many people who think all their gaps should be a perfect 3mm in width or something. What you’re are looking for is consistency and proper alignment. So if your trunk hatch has a 1/4” gap on the left side, it should be a 1/4” gap on the right side as well. The 1/4” gap between the two doors on the left side should match the 1/4” gap between the two doors on the right side of the car. Some of the gaps are quite small. If you see a gap that’s larger than 1/2”, something is wrong... But I do think some people have unrealistic expectations with some of this or it’s their first car and they have this giant checklist, but truly don’t know what they’re looking at.
We took delivery yesterday and our fit and finish on our new Y is perfect. All gaps match up from side to side, doors and trim line up as they should. Probably has the best panel alignment of any vehicle I currently own! And I own several to say the least.
I would refuse delivery for dents or curiously mismatched panel alignments or anything that requires it to go to a body shop. On the other hand, I would probably not refuse delivery for paint issues. In fact, if the paint is bad enough where the car needs to be repainted, that’s almost a bonus... They have to pick up the tab for a new paint job and you could have the chance to get a one of a kind Model Y by repainting it some crazy color that no one else has.
