A) Sorry, I wasn't counting the 400hp vehicles owned by people compensating for other problems. Maybe they don't downshift. Of course, who cares because they even get sucky gas mileage downhill.
B) And, you don't know if the Camrys were "struggling" or in no hurry. Of course, they could have been OVERloaded, heavily laden with gold bars from the savings that their Toyotas have delivered over the years.
C) "Uphill all the way" over 200 miles from 1K feet to 3K or so feet is a 20 or so feet per mile. No big deal and therefore I'm quite sure you're full of crap.
D) I don't believe you, anyway. I've driven one. Nice car. No problem with power.
