a car's value is the price one would pay to get to drive one.
it's very subjective. if you thought you got a great deal, then
you did.

but the reality is at the end of the day the accountants who
have virtually no interest in cars will add up the dollars and
count the profits. there's no such thing as a good deal to
the customer. they will make a profit some way or another...
otherwise, they dont know how to do business.
