Porsche Services in High Wycombe

From routine servicing to complete engine rebuilds, everything we do is Porsche-specific and carried out in our own workshop in High Wycombe. Every car is looked after by Lawrence McGovern and a small team, using genuine Porsche parts, Mobil lubricants and PIWIS 4 diagnostics.

Our Services

We work on every Porsche, from air-cooled 911s and the front-engined 928, 944 and 968 to the Boxster, Cayman, Cayenne, Macan and Panamera. Most of what comes through the workshop is a 964, 993, 996, 997 or 991. If you’re buying, we also carry out independent pre-purchase inspections at the workshop.

Commitment to service

I started Chelsea Carrera with one goal in mind: to provide Porsche owners with the kind of care and attention I always wanted for my own cars. It’s not just about servicing; it’s about trust, detail, and making sure your Porsche continues to feel as special as the day you bought it.
