Excellent service and repairs as usual on a ten year old Porsche Cayenne S. The knowledge and quality of service was exceptional. David Ryder kept me fully informed of the issues noted, the progress of repairs and the timing when the vehicle would be ready. Radiator shutter assembly , which had stuck, had to be replaced resulting in overheating, some bolts on the engine were cracked and leaking oil, and a brake fluid service was performed.
