Work is always, always done right, and right the first time. Dave has also pointed out things that needed attention, that I wasn't aware of. On my last visit, Dave repaired the headliner inside my Cayman, which hung down loose from the car's roof. After the repair, the headline was perfect. I never have the feeling that I'm being ripped off, as I was when I had to take the car to the dealer for warranty period service. I hardly ever post online reviews, so you know that Modderman is a great service business
