Volkswagen beatle 1963 derelict

[Ma1047]

There's a derelict, Volkswagen beatle 1963 that I got after beating the soldier dude. Got all the parts. Went to the garage to build it. Neither the guy who builds them said anything about it, nor the game is letting me restore the derelict.. What should I do?

So I found all the parts for the Ford Mustang derelict and now it says go to your garage to restore the Vehicle but when I go to the garage it’s not there and when I press on the derilect slot there’s two options of restoring a derilect or selecting a dirilect but it won’t let me present either, can someone plz tell me how to get my direlect?
