Shop manager Andrew Gunn and tech Fernando took my damaged M3 and made it into an awesome track car, removing the engine and entire drive train and suspension, and installing everything into another donee chassis, after removing the engine/trans/suspension of donee car. Andrew even had the wiring harness harness completely re-done. The ‘new’ track car is 800lbs lighter, tighter, stiffer and quicker. They did all this in about 2 months, connecting me to a specialist who built the cage and strengthened the rear subframe. That was an enormous job, really well-done with no aggravating delays.
