"Looks" would be considered the car's cleaniness, wax job, paint job, overall exterior condition, lack of dings/scratches and fingerprints, wheels, interior appointments like carbon fiber trim/gauge faces, steering wheel, gearshift knob, body kit, clear lenses, city lights, etc.
"Performance" is the car's power and handling which would be the addition of sway bars, strut bars, cold air intake, computer chip/software, rear-end gear change, short shifter, turbocharger or supercharger, springs, shocks, X-Brace, brakes, rotors, etc.
Your answer doesn't have to be based on what you have done to your car or how much you have spent on any aftermarket equipment but simply where you place the importance or how you feel about your car.
Rate both and make the two equal 100%.
Post your two percentages in the "subject" box for easy referral.
Example: (L) or Looks 45% (P) Performance 55%
Don't be influenced by other's responses. Be honest - Your answer (and the others) may suprise you!
