Paragon, based in the East Midlands (Northampton) offer MOT, servicing and repair work to American vehicles including SVA preparation and full diagnostics and brake upgrades.
They say:
Paragon MOT & Service Centre opened in early 2005 and has always worked on a wide variety of vehicles including American ones. Not surprising as we are owners and drivers of US built vehicles ourselves. We are also active members of a number of American vehicle-specific clubs.
Paragon has extensive knowledge of American cars and trucks, and the US-specific diagnostics equipment necessary for many American vehicles.
We provide fixed-price servicing for older vehicles - oil service and annual service - or services in accordance with manufacturer schedules for later ones.
We also have our own reliable parts supply network from the US and carry service items in stock for many Chevrolet, Pontiac, Dodge and Cadillac products. We also hold stocks of American grade oils and fluids.
