This is my 4th sight unseen purchase. The first 3 were 2 BMW's and 1 Porsche. While the first 3 examinations were done by the nearest dealership and ultimately sufficient, Rolf's was a cut above. From the beginning conversation with Kassandra to the final pictorial review summary, the detail, communication and data was superior, more conclusive and more economical. I only wish they were in Oklahoma!! 6 stars from this guy!
