While I do agree that we are not the MAIN reason for climate change, but SUV's, well cars in general create A TON OF HEAT!. Your engine heats up all that metal shimmering off the sun, heats up. The black tops and roof tops heat up. Then you have tall buildings. I do not think Co2 is the cause for this heat, but the world is just like a computer case, it has things inside of it witch are hot and cause the air inside to get hot. The earth would most likely be cooler if the ground was not covered in cement and metal.
The heat delivered to the Earth by the Sun would be absorbed into the geosphere's energy system, regardless if it hit the top of a car or a leafy plant. In fact, using your premise it could be argued that the cars are reducing temperature, since all the car rooftops are increasing the Earth's albedo!
Not to offend, but to educate: The global warming argument is that increased CO2 adds another "blanket" over the Earth which brings us slightly closer to a closed system. Science primer HERE
"The heat delivered to the Earth by the Sun would be absorbed into the geosphere's energy system" Your point? If ALL the heat was absorbed then the earth would not get hot. Nothing on the ground would get hot. Are you trying to say that all this concrete metal and cars witch absorb heat and magnify it are not contributing?
