I think I could conceive this sort of treatment if you bought a car with a collector's perspective, knowing you will have the luxury of only being able to take it out when the weather is nice and mostly do a very limited amount of mileage on it every year. Maybe this is the perspective this chap had when he bought it. Who knows... in 20 years time it might be like some of the XR 2's we now occasionally see on ebay or at shows with a mere 5 or 6000 k miles on the clock. It's difficult though to see things this way when they are new cars.
