Selling lease car to private party

ending lease in another 2 months – Vroom and caravana not paying close to the buy out price.
Can I sell to a private party just to save on disposition

How does the process of transfer works in this case – so there is no double tax and the final owner bears the tax.

I did this last year with an Audi. Audi doesn’t allow 3rd party transfer, so I had to buy the car and re-sell it. I think this is pretty standard across brands, but maybe some do allow it. Tax varies by state. I had to re-title the car before I could transfer it and the buyer and me both had to pay tax. I think CA gives a 14 day grace period during which if you can transfer it you wouldn’t have to pay double tax.
