Probably the Jester.
I had to go back and look through the wiki because I could not remember a car design I’d call my favorite. I love boxy 90s cars but something was just not right with what they put in SA. Apart from the Jester, only the motorcycles looked nice and Blista looked nice (though it peaked with IV).
Did it have that fiery exhaust in the middle of the trunk area or was that just in V? Only reason it remains in my brain drive, bitchin’.
