Mine has been a daily driver for the past 12 years and I'm currently north of 185k miles. Been on Prime for probably 12 or 13 years and this daily driver discussion comes up time and again. I've always been of the mindset similar to Batmans post above, but today I saw a summary from a new book The Top Five Ways to Turn Money into Happiness (
http://www.linkedin.com/today/post/...he-top-five-ways-to-turn-money-into-happiness) and it purports to delve into the things that make us happy. Their point #2 is "Make it a treat" where they say "When wonderful things are constantly available, we become less able to appreciate them. Limiting access to the things we like best helps renew our capacity for pleasure" which presumably suggests that us daily drivers aren't actually appreciating the car as much as the ones who take it out on special occasions. So, to extend Batmans analogy, I presume its like saying that we'd get more appreciation from having sex once a week (as an example) than every day .. which I think it sort of a 'quality over quantity' argument. It's not exactly in the same category as 'saving her for the next guy' but I can see some validity in the argument .. but there must be an optimum point somewhere in between the extremes.
