In GTA Online, how do you get rid of your Annis Elegy RH8?

I got mine impounded then left it there to be destroyed

Here's a tip if you fall into the 'Elegy Hole' and want to keep a specific one (i.e. You have a custom you want to keep but lose the extras.)

This method uses the 'replace car' method. The nuance is that matching cars in the 'replace car' menu are listed identically. This method helps you identify a specific one using the police impound.

1. Take the Elegy you want to KEEP and get it impounded. (Have fun with this step).

2. Once your good Elegy is impounded go out into the world and fill your garage until it's full.

3. At the 11th car you'll be asked which car you want replaced. The Elegy you want to keep is safely stored in the impound and will say "(Impounded)" next to it in the replace car list.

4. Replace all the unwanted Elegys. (Elegi?)

5. Go to the impound and get your custom Elegy back. (Like a boss).

(Note: I suppose you could let the impounded Elegy be destroyed and file and insurance claim but what's the fun in that? "Go get that muthafcka, fck the police!")

As of GTA Online Update 1.36 you can sell the free Elegy RH8s. You will not receive any money for a bare car but any modification you bought from LS Customs will be refunded at 50% price.
