Incredibly knowledgable and attentive to detail. Having a fleet of cars, vans trucks and 3 mobile and in house mechanics I must admit "Welwyn Merx" is your full stop REAL Mercedes specialist who has exceeded my expectation.

It's rare that I feel the need to write a review about a company, service or experience but Welwyn Merx look after my Mercedes E Class convertible so well I felt the need to acknowledge them. I highly recommend them over and above other Mercedes dealers and surrounding independent garages, truly trustworthy and good at what they do, a breath of fresh air. Keep up the good services guys and a special thank you to Phillip for his attention to detail.
