You can potentially save $3000-4000 and have a very reliable rust-free car.
I suggest buying from a dealer via auction, make an offer, or buy it now.
It is also a very good idea to pay for a third party mechanic after purchasing to verify the car is in good working condition.
You can then have it shipped to your door for anywhere between $400-800.
If you run into any issues, then you can contact the seller ask them to refund you the repair cost of the undisclosed issue. If that does not resolve the issue, then escalate the problem to eBay and they should almost certainly side with you, the buyer.
