I would not consummate the deal on eBay UNLESS I had a signed document/contract from the seller with every detail, expectation, condition clarified in writing.
I don't know about the inspect my ride, but I'd be concerned it is superficial... Better to find a local mechanic you can talk to first
The deal should be contingent on YOUR impersonal inspection, AND your each antics inspect, with any deposit fully refundable.
All in writing, any deposit with a credit card
Keep it as simple as possible...but no simpler.
