So this is super anecdotal, but there's a Tesla sales and service center like 5 minutes from my house so I drop by on occasion to do a personal quality check on the 3s I see in the lot waiting to be delivered. IMO this is misaligned. I see 3s regularly that don't have a gap that big on the left side. Most of them are equal on both sides. If the right side gap is smaller, I say put in a service request.
The lack of rubber trim is normal, but that looks like a very big gap to me. Unless of course the right side is the same, in which case, great!
