Here's my highly non-scientific graph plotting 0-100 kph (same as 0-60 mph) versus car base price in Cdn $. I think there's some errors on it but it seems generally ok.
Turns out Price Cdn$ = 147119*exp(-0.234*(0-60 time (s)) is a reasonable guestimate for new car prices?
Anyway, the geek in me thought this was neat
PS: The 1993 Geo Tracker with its unbridled 82 HP of raw fuel injected prowess is my current ride, but I'm in the process of upgrading to a WRX. This graph was part of my process and one of the many reasons that led me to a WRX.
