I am 72 years young and have similar thoughts to you. I was a keen and avid Japanese fan with the likes of Nissan 200 sx (S12, S13, S14, Primera eGT and Skylines including a R34 GTR I upgraded to 430 BHP.
Now have my S-Type, which I absolutely adore, even though it does take some regular repairs, resets etc, to keep it running. It is a gorgeous car, of 16 years of age and has 65,000 mls from new. Needs battery (12 months old only) constantly being put on my CTEK charger/conditioner as with most S-Types and many other Jaguar models, they suffer badly from low battery charge due to the over zealous discharge when not in constant use.
I would not be without the older style and leisure of an S-Type Jaguar these days.
Best Wishes and Regards, John
