If you don't have a headliner putting something up there will help a lot. My car doesn't have one and it is the biggest reason for being medium rare in the lanes. On the street its never much of an issue but it always gets me in the lanes.

And painting the roof white. Look at all UPS trucks. There's a reason they paint the roofs white. lol
