Onyx Autocentre is an independent garage on the Deseronto Trading Estate in Slough, just minutes from the M4, M25 and Elizabeth Line. We service and repair every make on the road. And we've built a 5-star Google rating doing it.
We're at our best on the day-to-day stuff: oil services, timing belts, brakes, tyres, batteries, MOT prep. The kind of work that keeps your car safe and stops a small bill turning into a big one.
For the technical work our technicians run main dealer-grade diagnostic kit, an in-house 4WD dyno and years on the VAG and BMW platforms. Stage 1 remaps to engine rebuilds. Same workshop, same standards, every time.
Ferrari, Lamborghini, Aston Martin, Bentley and Porsche are regular customers here too. Owners from Windsor, Gerrards Cross, Taplow and Cliveden bring them in for servicing, alloy work, mapping and dyno sessions. Same care, same paper trail, whatever the badge on the bonnet.
The waiting area has proper coffee, Wi-Fi and Netflix. The lads on the tools will tell you exactly what your car needs and what it doesn't. That's it.
