It's too nice to part out, it is the last year for these, last year of the uber reliable W124 E class, it has new good Firestoe tires, mileage is not high at 181k, and it has the best possible paint and interior colors, has the desirable third seat and would look VERY slick, when cleaned up.

For $650 for all of that I think it is worth it to buy and repair.

I'd do it quickly and NOT try to beat the guy down a miserable $50-$100 bucks on his price. (Though CL is notorious for bottom feeders and cheapskates...)
