Thanks - in perusing this forum I didn't see many high mileage boxsters - so this begged me to ask the question about driving 100K plus miles.
Now recently when I was in my local Audi dealership the salesman asked if I had ever bought a car there - and I said yes, but I bought it one part at a time
By my math, if I paid for the car once in a purchase and once in repairs - I bought two cars - I just have one VIN to show for it.
