I'd go with T-8's
Is there specific area where the car will be while you work on it ?
One issue is the hood will usually block a lot of light
Some people have mounted a set of lights at an angle on the ceiling to direct lights down & under the hood
Others use a portable light setup for more light
I have a 24x30 workshop with 8' ceiling. General lighting is provided by six 4' two bulb flourescent fixures. A corner work bench gets another same light fixture directly overhead, as does a assembly bench floating in the room. Also there are two reeled worklights that hang from the ceiling - at the ready to be pulled down and put direct light where needed.
