Hi - Our forum system is a little kerplunk at the moment so here is a "new post" which is really a response to your post (my response is in Que whatever that means)
Jaguar Journal is a publication that has a classified add section where your car would be seen and desired by an enthuisast. 910-398-3620.
Some of the very early model cars are less common (exterior bonnet latches) so there is a chance that informatoin is true. If you post the vin # I'm sure lots of folks here would be able to tell you intersting things about the car.
This is a link that breaks down the models and informs by vin# if you want to do your own research

This is a classic auto insurance company, they could probably point you in the right direction to have someone appraise it to make sure you are close to fare market value when you sell it.
Good luck - I'm sure whomever owns it next will take good care and really enjoy!
