I'd only buy it if I could get it in my driveway for $2k. If you had a nice S420 that car would be a gold mine. Lots of little parts add up that you could borrow. Not to mention if someone hits you, you have good sheetmetal!

The rear view mirrors are $200 each salvage for example. The wood looks decent thats a few bucks.
Don't forget the interior is shot, looks like $5k their at least...
I never made any money parting cars out, waste of time IMHO. But if you have one and need a little something here or there it adds up.
