I had been a happy customer of Nurburgring for several years. however within the past year they have done physical damage to my vehicle twice. The first time they broke a skylight on my vehicle, and admitted fault and repaired it at their cost (though I was without my vehicle for about a month while they repaired it, with no compensation). I understand accidents happen, so I continued to use their services. Unfortunately they now put a very large dent in the roof of the vehicle (about an inch deep and 6 inches across). This time when I asked about it (politely and reasonably) Juan got quite upset at me, told me they couldn't possibly have damaged it, and refused to even look at the damage, let alone do anything about it. He in fact started blaming me for daring accuse him of the damage (which I know for a fact happened while it was in their possession, and due to the placement could really only have been a hoisting incident, it is a tall vehicle, but that's no excuse.)
I will never take another vehicle to Nurburgring again, and I recommend anyone who cares about their vehicle doesn't either.
