Ownership & Maintenance
I’ve owned the car since 2013. I purchased it from my brother, who had it in Pebble Beach, California since the 1990s. It was always garaged and kept in excellent condition there as well. He completed most of the modifications and upgrades. There was one owner prior to him. I have all service records documenting the car’s history and maintenance.
