With over 50 years of combined experience there really isn't much we haven't seen or diagnosed here. Often times dealerships will send people to us after they can't figure out what's wrong with their car. We're not limited by a standard diag tree/procedure and are free to really think outside of the box. Combine that with a much more in depth understanding of how cars work and think & there isn't much we can't figure out. A lot of dealerships won't work on modified cars. They're scared of them. We sure aren't, we love them! Don't let the dealership tell you your headlights are the reason the car is misfiring (actually happened). Let us figure out what's actually wrong with your car.
