I've used Caliber Motors for some time and have never had a problem. If you tell them to use UPS Ground, they do it. If you don't tell them, you might get something else. I've always dealt with Al Trevino.
I recently bought parts from MBParts because of the free shipping. Everything was great except that one part didn't get shipped. I was told to call them rather than use the Web ordering process. The people who handle the Web orders apparently make too many mistakes.
The prices were great as are FastLane's.
