you can go to any shop and if they want your money they will work with you
The two shops I first got estimates from did not even mention a "spot repair", and my FOAF said that it's common as some shops will only quote a full repair and not the cheaper options. My third estimate was at Maaco, which I did not seriously consider mainly because of the bad things I've heard about them. Rather than re-type that story, here's a cut-paste of what I wrote on a local board:
"For those who care, just for giggles I went for an estimate at Maaco and it was a learning experience. I admitted to the guy that I had multiple estimates, all in the range of a kilobuck, and that I thought they were high.
He immediately chimed in with "we get that all the time" and that "most body shops will not even discuss the cheaper options" since the vast majority of their work is insurance.
He gave me three options. First is to repair to insurance standards which was almost as much as the other two. The second is not to remove the left rear window and trim but mask them off when painting, which was about $200 cheaper. The third is what he called a "spot repair" where they repaint only the repaired area and blend it out about 18" but in my case they would stop at the edge of the left door. He assured me that most people would not notice it, but that anyone familiar with body work, like the person who appraises it when I trade it in, would know it was done. This one was just about half of the original estimates.
Now a client recommended a place called Paintcrafters (anyone have any experience with them) and I phoned them and they say they can do a spot repair which will not be obvious to anyone. I plan on stopping out there today or tomorrow unless I hear anything bad about them.

"
My FOAF did a spot repair, but it is so well blended that it's really impossible to tell. It was far less than the estimates but I'm still p*ssed that it happened and I'm far more careful about where I park now.
Here's the "after" shot of the area:
