It's still and 6 or 7 year old car, even if it only has 500 miles on it. The price doesn't seem out of line to me, but going any higher would begin to seem out of line. The value of these cars won't go up for for another 10 years or more. That's when they will be even more rare and become of age.............

Since I'm not thinking of selling it, the value / price doesn't matter to me. What matters is that I still love the car and enjoy driving it.
