Yes, of course you can. The ownership of the car (in the UK) would then need to be changed from you to your relative. In the UK, details would need to be sent to the DVLA (Driver & Vehicle Licensing Agency), which is probably a department differently named if you are living in a foreign country.
If you own the car, you can sell it for whatever you want. You can even give the car as a gift to someone.

Sell it to a recycling company. That's right, you can sell them to top junkyard company and they will pay you top dollar for it.
