I just picked this 1970 521 up a couple weeks ago and have been having a blast driving around in it. It's kinda hacked together, but I'm slowly redoing it and making it more my style.
When I got it.
Repainted it and added different wheels.
Lowered the front another 2-3". It had already been lowered when I got it.
The paint that's on it is chalkboard paint so that's always a hit with my friends.
