Can you confirm spark and ignition timing? Is the cold star injector squirting?

There isn't a lot of complex technology in the '78 450SEL, just a lot of brilliant simplicity. if it looks solid it probably is. $2000 for something close to a driver is probably a deal if that's what you're after. I don't think a non-6.9 is worth the cost of restoration.

Is it a Euro car that has manual AC controls along with fabric upholstery? Regular cloth or velour?
