how to define fast? , and how to define cheap???
Fast as in top speed? acceleration? cornering speed? or everything??
fast car from stock standard car, or modded car? highly modded car??
Without a fixed parameter, this discussion will go on until cows come home, go out, come home, etc....
Are we looking for bigger bang for the buck??
one way to do it could be like
1. take price of the car (used or new) - say 50k
2. take the real top speed of the car (don't refer to speedmeter, as some meter tipu-tipu one, or the car can't really reach that top speed) - say 230km/hr
then analyze like this lor...Since "cheap" is important, compared to "speed"....so
car A: 50k for 230km/hr top speed........means 1k paid for 4.6k per km/hr
car B: 25k for 180km/hr top speed........means 1k paid for 7.2k per km/hr
car C: 100k for 220km/hr top speed......means 1k paid for 2.2k per km/hr
I know there will be many motorhead professor in ZTH that might disagree with this.....so fire away
