1983 Mercedes 300-SD Pricing

[LSlone777]

Hi.

I've checked the pricing from 2 different Internet sources regarding the value of this Mercedes and got 2 totally different prices.

Edmunds quoted $1,024 (trade-in), $1,838 (private party), and $3,209 (dealer retail).

NADA quoted $4,500 (trade-in), $6,700 (average retail), and $8,750 (high retail).

And that's with the exact same data inputted.

This is a 1983 Mercedes 300SD Turbo Diesel, 150,000 miles, sunroof, automatic, 4-door.

Which quote would you say is more realistic? Is there another Internet site that you would recommend that I go to for a more accurate quote?

Thanks for your help!
