On the contrary Robert - that..................... 'can we run that on the
dyno for you' is a great idea, because then you could pick out which 2008
Framus WindZing actually had more power than the other identical cars.
New sales tool !
Bring it on !
You're a genius, executive material even !
They should offer you a big office and a fat pay check for bringing this to
the automotive sales world.
Free dyno runs ! Pick the car that 'really' goes the best compared to its
siblings !
Blah blah blah !

I know exactly how you're feeling Robert. I had the same epiphany when I
drove a 2.5 Subie in a MultiVan at SmallCar, and again when I drove Paul
Guzyk's 2.2 Carat Automatic here at home.
Aye caramba!
I'd love an opportunity to try a Zetec too. Anyone?
