well thats astonishing for two reasons, one you must have driven it very slowly or had cruise on most of the time, and two, even though modern oils are better, 26k without an oil change in a performance car is a bit of a no-no in most peoples books. I just hope it doesn't come back to bite at sale time.
The speed that you drive is pretty irrelevant to how long the oil lasts when driving on public roads, more to do with rpm, operating temperature and friction and there are a number of factors that can help engine longevity. For instance, how you treat the engine whilst it's warming up, I don't push beyond 2500 rpm nor use full throttle until the engines at normal operating temperature.
As for biting me when sale time comes, it will depend on how rational the potential purchaser might is. My car uses a minimal amount of oil, about 1 litre in that 26000 miles, compare that to my last Zed, an ex demonstrator, which used 1 litre for every 6000 miles. As a Mechanical Engineer, designing mechanical equipment, I know perfectly well which engine is wearing and fairing better.
The OP was asking a genuinely important question and yet there are posts above which are based without any scientific reasoning, just irrational fear based on advise given when the Austin Princess was avant-garde. Yes my 26000 miles is exceptional but 22000 is not, just slightly above average for a modern petrol engine.
I wouldn't fault your logic but sadly you hit the nail on the head when you talking about 'rational' and 'purchaser' in the same breath LOL. You only have to look at the caterwhauling on here about dealer servicing etc.. as if its a bloody spaceship instead of a two-seater 3-series LOL
