You have been scammed. My guess is that you found a great deal on another site (craiglist, facebook marketplace, letgo, offerup, et al) and the "seller" told you the transaction would be "completed" on eBay "for your protection."
The seller then tells you that he/she is deployed but the vehicle is at the eBay shipping center ready to ship at no cost to you. It should arrive in 2 days, 3 days tops. You then have 5 days to decide if you want to keep it and only then will the money be released to the seller. If you don't want the vehicle after trying it for 5 days, shipping back to seller is free also. You received a fake invoice with eBay logos on it. You were instructed to pay with gift cards (untraceable, just like cash). You gave the "seller" the gift card numbers. Your money is gone. There is no vehicle. Just pictures the scammer got off the internet.
First rule: If it sounds too good to be true, it is. If the seller was a real seller and actually had a vehicle that nice at that super low price, he could sell it in an afternoon locally. No need to put it on the internet.
Next rule: All legitimate eBay transactions BEGIN and END on eBay. Period. No exceptions.
