Man, nice BMWs you got.
I love the 1M, was really close to buy one, but one year wait was too much for me, now I kind of "regret" it. Maybe later down the road.
Your 84 looks amazing for it's age. I have a 732 from 81 sitting in my barn, rusting away. I mean it's full of rust, everywhere, much worse than your M3!
It will be a project when the new garage is ready...
