We have inherited a Jaguar S type which my father-in-law had made notes that it was registered 4 months before the Browns Lane production line started building the S type.
 
	It was owned by Jaguar for over a year and he thinks used as a prototype test car at Jaguar.
 
	The VIN is SAJAC01FXXGL20900  he noted the X means The Whitley Engineering Centre in Abbey Rd.
 
	Can anyone confirm this? and have any further info please?  The car is now for sale.
 
	Thanks
 
	Ivan
