LOL - that's exactly it. I have an E39 530D M Sport - perfect mechanically but paint needs a bit of TLC or replacement lol
I'm in the same boat, but it always comes back to "what are you going to replace it with"
Gonna paint it and drive it a few more years - it's actually nice to have something that now is different, and to be honest I still love how it wrap's around you and make you feel connected to whats happening - very few cars left like that coming out now. It's at the bottom of it's depreciation also.
