The 170 was 3000mi away, sight unseen, but it was new, 15mi, full warranty. Only problem was I found a small chip in the pass door, it did not buff out, looks like it took the clear coat off. I may attempt to apply new clear on the chip and wet sand it down. But it is very hard see/find, I didn't notice it until I did the decontamination. I may just leave it.
As far as a used car, I agree with you guys. Buying used boat unseen, I will be polite and not comment...
I sold my M6 on ebay, great platform, worked out extremely well. Guy flew in with his wife, took the shuttle bus to the station nearby, I picked them up, we called ebay to transfer the funds, he drove off happy. Great way to do it, he had the option to back out if he found a problem.
