How to rate cars

[ddiinn]

Hello everybody this is my first post so i hope i am asking my question correctly.

I am making a computer program that has a database of supercar's, and now i want to create a way to give a car a score, and then compare it with its price, so i can say which one is the best to get. How do i rate a car ? which perameters matter the most ?
this are the things i used in my program:

Model
Company
Year
Engine(Number of cylinders,Volume,Power(BHP,RPM),Torque(Nm,RPM)
Gears(Amount,Manual or Auto)
Drive
Dimensions
ABS(if it has it or not)
Speed(Maximum,0 to 60)
Price

thank you.

I would rate by power, 0-60, and then the price.

You're forgetting luxury features aswell. And it should also depend on what segment the car is in. If I need a family car with alot of cargo room and safety features, I dont think 0-60 matters as much.

Oh sure, but my software is only on supercars.
also, everything should have siginificance, just the question is how much ?, like how can i get a score which is based on the importance ?
for instance if the 0-60 is the most important, and i have a car with the best 0-60, how should that come into effect in the cars grade ?
