this is an interesting picture in that there is a lot of natural green in the picture, but there is also a green cast and a bit of a blue cast. the trick is to keep the green you want and get rid of the green you dont want. i used a combination of color balance, channel mixer, hue/sat, curves and even some of those more than once. on the final color balance i turned off the 'preserve luminance' and adjusted without it.
a couple things to note here; notice the two lighter colored cars. they are both actually white but are tinted quite a bit, especially the one on the right. murray did a very good job of correcting those. i let one of them remain a bit green in favor of some other adjustments on the pic.
the other thing to note here is if you are actually familiar with the actual area you have an advantage of seeing how lighting actually affects everything and see whether that red brick is really bright red or is it worn a bit... little things like that can help you tweak this picture on your computer.
