Love to try Don, just don't know yet what chances are on any of it yet, if paper even still exists or how receptive they may be? .
For all I know, it may be a cranky broad with the access to the info so perhaps if we try a nice simple one by Vin first, we can send flowers etc. and find out an idea of what may be there then try again for more? .
Just a thought but do you happen to have any paperwork on your Caprice purchase? . Often the sales document will note the trade vehicle Vin too? . And not to make you feel worse but do you recall what trade value they 'allowed' you for it? .
