I'd have no issues buying a Porsche if I had the money lying about. Having ridden in a few, I find most of them very dreamy cars.
I find the latest Boxster S a particularly delicious drop-top, but I'd certainly have to jump into the next tax-bracket to justify the money dropped on a joyride like that...
I do recall that some models do have longer than normal drain/filter change intervals due to the oil system capacity, but if you're driving the s**t out of the car, then one should adjust accordingly.
The gent did sould like an "infomercial", though.
