I'd take that double offer and run...i can pick up a pristine and original 67 GT500 for less than 40k gbp.
Only an original stamped Shelby would fetch serious dollar, those with complete paperwork as well.
I'm not looking to buy any more cars, but if one of the following pop-up i'd consider it seriously :
- a 67 Shelby Mustang GT500e
- a 69 'The Judge' Pontiac GTO
- 70 Dodge Challenger
Any one of the above in the right colour and with all provenance...i'd not hesitate for a second !
