The things we see on classic cars is amazing sometimes.

Previous owners of this Pontiac GTO installed aftermarket oil pressure and coolant gauges. While that’s ok to do if necessary, it’s absolutely not a good idea to run the oil pressure like into the car and underneath the gas pedal. If and when this fails, the driver will get a hot foot bath of engine oil while the engine loses pressure from a blown line. Not a good install that we need to repair, to say the least.

1978 Pontiac Trans Am finished and delivered back to owner. This is one that shows you good maintenance goes a long way. Original 1978 drivetrain still running strong.

Customer had us flush all fluids throughout and replace. Engine oil, coolant, brake fluid, transmission, rear differential and steering all refilled with fresh fluid.

Let us do yours,

Not our typical or correct approach in terms of process for restoration but we are doing this 1971 Satellite right when we work on it.

Gotta love that 1970’s green,

Nice 1978 Pontiac Trans Am we took in for work today. 400, 4spd, WS6 package, T-Tops, A/C, power windows, etc! This should hopefully be a fun and quick job. Manager Jon got this one in for one of his family members who moved to the area. We will surely take care of it as we will see this car locally around town in the future.

We may be biased on this one but these are some of the best looking valve covers out there. These are Ansen cast aluminum valve covers for Pontiac engines that we custom painted Pontiac engine blue and finished with PPG Deltron clear.

Our guys in the body shop worked hard on this Plymouth Duster. Lots of detail work to get this underbody fixed and converted to B7 Blue. We can’t wait to get this car running and driving. This one is going to be a true driver’s car.
