Help me price this 190

[benhogan]

I am being offered an 89 190e 2.6

here is what I know....
no accidents, no rust, a/c shot, 240k miles, good tires, adult driven
needs-wheel bearings
needs- according to the owner, something that keeps the belt tight. tensioner perhaps?

questions- did this car come with a tbelt or tchain?

I will probably offer $500. The color is a boring yellowish cream
