I'll post my
also.
Available light is your friend, use it to your advantage. Keep the sun at your back on bright days, plan your back ground according to the suns position and time of day.
Long and / or exessive shadows make poor photos, take photos from 11 am to 1 pm on bright sunny days.
On overcast days, the clouds act like big light diffusers, it is possible to ge some great shots on overcast days.
Some cameras do not give "true" colors, so play with your camear and subject a lot to see what works for you and your subject.
If you have a white Challenger, a LARGE bulldozer makes for a great Vanishing Point type background. That one is for Lucy and Carl.
Now go play with your cameras and cars, after all,
lol,
