FWIW & IMHO:
I have no experience either selling or buying on E-bay but these are my viewpoints from observing a lot of transactions, good and some not so good.
Reserve: It would be wise to set a reserve, in my opinion, to avoid being forced to sell if the bidding does not go as high as you expected it to go.
Disclaimer: A notation that you have the car advertised locally and reserve the right to sell locally.
Start bid: Setting too high might keep people from bidding and if you end up with no bids, it would seem to me to be harmful the next time you run the car, if you do. A low starting bid would be much better for you than a high starting bid.
Please keep in mind that I have no actual experience buying or selling off of E-bay, these are just my thoughts in general on such.
