Our Mercedes-Benz servicing follows factory specifications using genuine parts and Petronas-approved lubricants. Each service includes comprehensive diagnostics with STARView visual reporting, digital service book updates, and optional service plans. Customers receive detailed quotations covering routine maintenance and recommended additional items.
Technical Diagnostics
We employ Mercedes-Benz STAR diagnostic systems for accurate fault detection. Our master technicians interpret error codes and perform electrical system analyses. This includes air conditioning diagnostics, ECU assessments, and complex electrical fault tracing using specialist equipment like Hunter 4-wheel alignment machines.
Mechanical Repairs
From routine maintenance to complex mechanical overhauls, our repairs use genuine Mercedes components. Services include gearbox oil changes, brake fluid replacements, and major component repairs. All work is performed by factory-trained technicians with warranties covering parts and labour.
Pre-Owned Sales
We offer hand-picked pre-owned Mercedes-Benz vehicles prepared to exacting standards. Each car undergoes comprehensive inspection and servicing. Our inventory includes specialist models like SLR McLaren and AMG variants, with full service history verification and warranty availability.

Our air conditioning service includes system drainage, recharge, and component inspection. Technicians check filters, hoses, and compressors to restore cooling efficiency and eliminate bacterial growth.

I've been using Avantgarde Automotive for the past three years now and cannot fault them. The service has always been friendly, professional and well priced. They've looked after my C220 cdi and my wife's A190. Knowing your getting the best service without being ripped off gives me peace of mind. Genuine manufactured parts with specialised mechanics who know the cars inside out- what else can you ask for? And now they've moved even closer to where I live. Happy days. I can thoroughly recommend them and will be continuing to use them for years to come.

Steve is a highly respected and regular contributor to the Mercedes Users Forum and has given me technical advice on a couple of occasions. Like most of our specialist independents Avantgarde provide quality services at an acceptable price and the proof of that quality lies in the number of regular customers who use their services.

Another service done! Excellent as always. Steve is very helpful. He explains things clearly so I can understand. Lovely clean garage. Always seems to be busy. A good local, reliable and honest garage. Definitely recommend them. Reception staff also very polite. Steve also fixed the DPF problem on my husbands Mercedes. My husband is over the moon.

Whilst I've not used the garage directly as an extremely helpful member of a certain MB forum I've had great advice from Steve which has solved at least one issue for me and he willingly gives numerous members on there free advice. Truly cares about MB cars! Their reputation is second to none from those we know who use them
