Very inconspicuous place. The workshop is superbly done and Nic really knows what he’s doing. I had him convert my speedometer to digital and install illuminated air vents and 3D Burmester tweeters. I felt like I was bombarding Nic with questions and he knew the answer to everything. He is just as enthusiastic about the results as I am. Simply 1st class! Laying the cables, etc. As original from the factory.
