A bill of sale, which I have a copy, is not valid proof for the LA Parking office. I'm going to call DMV and then the Parking office to see what's up. I sold the car with tags that won't expire until 5/11. I did everything on my part. I'm just a bit ticked that the new owner hasn't even registered the car.

So should I pay now and then wait to clear my good name and get a refund

or

Don't pay one penny?

By the way, this was my beloved Benz.
