I've used them lots as well. Very good, very consistent.
Classic example of a team that really knows its own business. Low markup, high throughput, easy way to build a good rep - it's a nice stable revenue base and relationship builder if you can just work in a professional way and be a litte enterprising re. forums etc. I'm not local to Lincoln (and I have no idea what their servicing dept. it like), but if I were, I'd look to them for servicing based on my experience with the Parts team.
