Re: Good Vendor / Bad Vendor
As a person that's recently been buying and installing a full array of parts, I can/would appreciate more transparency from suppliers where possible. I LIKE that OPGI lists 3 different makers of interior replacements, a sort of good, better, best. Trying to find the best, or at least a quality heater core, for a recent example was a lot of work. As Rick noted above, prices can be all over the place for what at least appears to be the identical article.
I will say that I've dealt with a bunch of the names mentioned above including the local O'Reilly's to the boutique stores and everyone has been great about returns and customer service in general.
