Mercedes 230SL in the workshop

I did quite a bit of mechanical work on this Mercedes at the end of last year, the owner recently took it for an MoT test and it failed but only on bodywork. I'm going to have an associate come and take a look this week with a view to repairing the passenger side floor, front frame "within 30cm" of the anti-roll bar and inner wing. The owner told me it's running like a top so there's nothing for me to do to it.
