I have a similar impression of Fredricks - The do an excellent job of restoring top-quality imports and supporting their customers who buy them. Also I think they are the source for a few of the quality components retailed by Hoye etc, in particular ROPS. A first class operation.
However - approaching Fredricks as a retail parts customer, my impression, based on a couple of parts inquiries, is they aren't very good at interfacing with the random customer. I felt the employee I talked to one time wasn't the right person to have answering the phone, he wasn't familiar with a common maintenance part. I gave up trying to explain it and ordered from Hoye instead. Hoye does excellent customer service. I think Fredricks prefers to be a supplier to Hoye instead of a competitor.
