The questions owners usually ask us first:

If it is water-cooled, yes. We specialise in the late-nineties cars onwards (996 through 992, 986 Boxster through to the 718 Cayman, Macan, Panamera and Cayenne) and almost nothing else. That narrow focus is the point: the tools, the diagnostic software and twenty-four years of experience all cover the same cars. Air-cooled and front-engined 944s we leave to their own dedicated specialists, and we will happily point you to a good one.

James Gunn-Carter topping up fluids on a 911 in front of the JGC Porsche Specialist sign

One ramp in 2012,
The same pair of hands today.

Like a lot of people in the trade, the story behind JGC Porsche starts early.

James Gunn-Carter, the man behind the business, didn’t just develop an interest in cars later in life; he was around them from the beginning. Growing up in Oxfordshire, he spent time at a local Porsche specialist workshop, getting stuck in wherever he could. Washing cars, helping out, learning by doing.

That kind of start matters.

It’s one thing to study automotive engineering, which James went on to do, but it’s another to already understand how workshops work, how customers think, and what actually goes into maintaining these cars properly.

By the time JGC Porsche was launched, the foundations were already there.

From James’s interview with D911.
