good morn,
You might get more views if you placed your advertisement in the sales section:

The asking price is up to you of course, but I think it unlikely that a laid-up Volvo 240 with no MoT might achieve anything close to £2,100. Project cars like that generally make a bit under a grand.
I wish you good fortune with the sale.
:-)
