Are repo cars worth buying ?

I won a bid on a repo car f. Currently waiting on the vendor to accept my bid or not. He did counter it but I'm not willing to budge on my bid because if I paid what the vendor is asking there wouldn't be much room for any profit. The whole point of getting a car from auction sight unseen is to try and find a great deal. This makes me wonder if it's even worth trying to bid on a repo car if you're just going to end up paying close to private party prices after all the taxes and fees?

Update. I guess the seller wasn't satisfied with my bid so the car is up for auction again. But now the minimum bid is where my maximum bid was. I assume I'm not on the hook for the car now if nobody else bids on it????
