OK, so what is "fair" anyway?
Is it worth it?
Well if 'worth' is making a profit, then probably not. The only important factors are the facts that it is "new" and almost no miles on the clock.
6 months down the road it becomes a low mileage car. Period. Worth a lot? Yes, most certainly. 30K? Most certainly not.
If the pleasure of owning one is what you mean, then probably not either; mine cost a bit over 3.5k pounds (OK, I was very lucky!), but I have EXACTLY the same pleasure for 1/10th of that amount. 1/4 or so would give you that same pleasure. OK, maybe some bills on the way, but not 30K!
If the Lotto threw the money into my lap tomorrow, would I consider it? Probably 'yes', even though it makes no sense at all, 'cept it's not a left-hooker, so 'no' on that count too.
