I think you've just made a very good point there, if you're putting above average miles on it, there's no point in paying premium money for a low mileage motor if its value is going to be deteriorated in a couple of years by your mileage.
Besides, personally speaking, I have never seen the fascination of a low mileage car. I understand fully that a low mileage car stands a better chance of being in better condition, simply because it has spent less time driving on the roads etc etc, but mechanically there's no guarantee that its going to be mechanically perfect, or any better than its high mileage counterparts.
My experience with low mileage cars is, whilst paint and interior have been very good, mechanically they have proven to be more troublesome than a higher mileage counterpart. Infrequent and low mileage journeys have caused engine wear that renders the premium paid a false logic.
As an example, a car that covers five miles a day will not reach a temperature high enough to rid the exhaust system of its condensation. Therefore, the exhaust will constantly have water sitting in it rotting it - this is not a problem with a car that is used regularly and long enough to burn off the condensation. Just an example.
I think it would be great to have a real low mileage car, but to be used as a concours/show car, not as a daily driver.
Save the premium, and find yourself a clean example with reasonable mileage, they do exist!
