“Theo has done a great job. He knew for what he had to look for.
The car had a defect alternator. Theo checked battery and cables at first to make sure that the problem is really the alternator.
Replacement of the alternator was quickly done and in good quality.

Communication in advance has been great. He arrived even far earlier after I have requested this.“
