Do tell how much do you think you can get for either 24 yr old car with 200k on it?

It'd help if you reply to my aforementioned questions. Of use these questions and answer them yourself.

It'd help to post images here on the brickboard. Upload images to your account and link them in your response with the target to the image.

Or use an image hosting site where you embed the link in your reply.

You can look up the value for your Volvo 240 on site like:
Kelly Blue Book - www.kbb.com
North American (Auto) Dealer Association - www.nada.com
Edmonds - www.edmunds.com
Ebay Motors

Other auto searching sites may also provide an appraisal function, perhaps like www.autotrader.com and their derivative site www.autotraderclassics.com. Use the search engines. Find your answer.

Use the brickboard search as innumerable threads exist on this very topic. Some threads are more like debates with all members chiming in.

Learn how to target the brickboard.com using Google with the expression "site:www.brickboard.com" no quotes in the search field.

Is it worth selling either one?

Only you know the answer to that. No one here on the brickboard can answer that. Other brickboard.com members may ask you a list of question, as I did, to try and uncover your motivation, and you did not reply.

cheers,

dud.
