Our Story
Built on Integrity. Driven by Experience.
With over 30 years in the industry, Jonothan Williams, a Mercedes-Benz Qualified Mechanical Technician, leads Advanced Williams Auto with a commitment to honesty, precision, and true craftsmanship.
From engine rebuilds to general maintenance and complex problem-solving, every vehicle is handled with care and expertise you can trust.
Because at Advanced Williams Auto — “Integrity Drives Every Repair.”
“In 2021, my car needed a new engine, and I didn’t have the kind of money other garages were quoting.
Jonothan gave me a fair price for both the engine and the labour, and the work was done perfectly.
It’s been years now, and my car is still running without a single issue.
I highly recommend Advanced Williams Auto — Jonothan and his team treat you like family.”
