Neonspinnazz;
About the only thing I would change in your evaluation is "Some drivers experience 50+ mpg".
That is completely wishful thinking with the 451. Maybe down hill with a tailwind.
The possible damage would be to convey unrealistic expectations. Car salesmen have been doing that as long as there have been cars.
There are so many compelling specs that it is completely negates the need to embellish.
BTW: The way you handled the absence of delivery is an example of your maturity, thus partly why you are embraced as an equal member of this forum of all those old people in their 30s, except that one person on here that is really really old, , , , I won't mention names or age (You know who you are).
