Did you bring this up with them ?! And did you pay for interior to be done too...?Would struggle to recommend BTD who did the detail. A lot of plastics left untreated, and didn’t do any of the interior. Also under the door handles hasn’t been polished, either. Car does look good, but it’s a 3 year old MB, not exactly difficult. 80% of the roof is glass...
