1987 190D Turbo questions

[JimmyL]

I'm going to look at an '87 190D that has sat for 3-4 years. When the current owner would drive it, he said it took 30 minutes before the turbo would start working. What does that sound like?
Also he thinks it needs a starter. When you try to start it he said sparks shoot out from somewhere. [either battery or starter. hard to understand what he was getting at]
Radiator is cracked at the neck of course. Are these the same radiators as the gasser 190?
Sounds like a semi basket case, but worthy.....
