Here's a tutorial that shows you how to make any car in the game damageproof. It uses a glitch with the taxi side mission and the car crusher to first create a 'ghost car', which you can then make damageproof by storing in your garage.
I believe this glitch only works on the original console and PC version of the game. To create a damageproof car on the mobile and tablet versions of the game, you can perform the same glitch, but you have to be on a regular mission rather than the taxi side mission. E.g. Drive Misty For Me.
