Thinking about purchasing a 1976 450SL
 

I am looking at a '76 450SL, 160,000 miles, good soft top and hard top. Owned by the 2nd owner, he said the injectors are not working and they are out of the car. Car has wire wheels and looks straight, no rust (AZ car). Interior will need to be replaced. They want 2K for it and I'll do a little negotiating about that price.
So should I walk away or take a chance on this car? I'll check to see if the engine is seized but he does not want to turn it over because the injectors are out, I see his point.

Regards,
Ed
