I was just wondering who sells VW bug parts like exhaust, master cylinders, alternators and of course some chrome stuff too.

Chuck at Mainly has said he is getting out of air-cooled stuff mostly, you might also try one of these other places.

Kinda stinks there won't be one in Chattanooga,  I do a lot of mail order,  Cleveland and dalton are to far away

I think, in Chuck's defense, it's a hard way to make a dime...

Over the years, more and more mail order of air-cooled parts have made it difficult for the little guys to buy in quantities that actually allow them to make a profit. 

I have a feeling he makes more off of a set of brake pads than a muffler and all the stuff to put it on with... and the pads take up a lot less space on the shelf.

I've dealt with Chuck ever since I've been into air-cooled VWs (about 20 years or so).  A lot of folks say he's an @$$, but I've always felt like he treated me fair.  Can't really ask for much more.  In the begining, his prices were competitive with mail order and the parts were good quality.  Over the years, the quality of the parts started to decline, the prices started going up and the result was everybody bringing junk parts back to him demanding their money back.  More and more mail order competition drove the profit margins down to the point that he really doesn't have time to put up with the crap.  If I had a business where I could make a 40% profit on Honda brake pads why would I want to mess with a junk part that I'm going to make 10% profit on and half the time have to mess with taking back the part because it was bad?  I really wish he still stocked high quality VW parts at prices competitive with mail order places like he did 20 years ago, but the reality of it is, those days are long gone.  I don't really blame Chuck for gettin' out.
