Thanks for the responses. I found a white over blue 250SL in Idaho that i purchased.
Yes the car in Nashville is the dark blue 230SL at Streetside. i found a shop that had good reviews on Yelp. The job they did was cursory at best.
They did report that the radio and the AC didn't work, and the transmission was slow leaking. But no pics, no compression test, no test drive, some paint problems. I decided to give it a pass, and keep looking. Finally found what i wanted in Boise.
