If it's got a bad headliner and a broken C/C, it's not mint.

I think price is way high, as you can find a true mint one for $5 K.

You can cruise at 70-75 or even pushing 80, but the car is working. If you want a road car, you should probably be looking at a 300D rather than a 240D. I use my 240D for commuting and it's perfect for that--top speed rarely above 55, with a lot of 35 and 45 mph driving. If you're doing mostly freeway driving, a 300D or 300SD is a much better machine.
