Not that I am a big fan of taking cars to dealerships, but I'm a little surprised by all of the bad press regarding Minuteman. I don't know if they've changed management in the last few years, but I've worked in Bedford since 1999 and I've had both of our VWs there a couple of times. Every time the service has been very good. The most recent repair was a faulty rear windshield on my 2001 TDI which was replaced under warranty. They subbed out the work (to Executive Glass), but I was very pleased with the quality of the work--you really would never know that it is a replacement piece of glass. The service manager even called me a couple of days afterwards to ask if I was satisfied with their work.
Also, I find that for parts they have better prices, even after the sales tax, than Tulley VW in Nashua. (That is, of course, for parts that I have to buy at a dealership. Everything is relative, right?)
