Doesn't look too bad in the pictures but they lie!
The first MK II I worked on was a high school friend that he bought for $100 in 1969 (from a guy who is now a friend and an SPF MK III owner) and it was a "little" rusty. We replaced the rockers with sheet metal screws as we didn't have a welder and used about 15 pounds of filler on a quarter when we couldn't bump it out enough. A quick BRG spray and off we went. We thought it would be a chick magnet, but two guys looking for two girls in a car that seats two (three if one will ride on the passenger lap...that offers all sorts of possibilities!) did not work as hoped.
Handling "improvement" was by adding heavier weight
oil to the shocks. The engine got the "by ear" tune up and a new carpet set went in and away we went!
