What Pete said. Generally, if the spotlights are only meant to provide more speculars to the car, get them closer to the object and crank up Power. Also, what spotlight settings did you use? How high is Falloff? Try using quadratic spotlights, too. I would change the relative positions of the two lights, too--cancellation is mainly due to symmetry, and if you look heads-on on the car, having two lights completely symmetrically, the car will be lit pretty flat. I don't want to sound too much like a salesman, but check out my lighting tut for some more information on highlights and lighting scenes with spotlights. Especially page 4, "lighting the glasses" might come in handy. -Sascha.rb
