Here's a thread from Bart outlining he bought the Griot's Garage kit to get a fantastic outcome on his black paint. It had lots of trail rash, and these products made it look amazing.

I bought the same kit he bought (from Amazon, but just last month I paid $120...now it's $199 ...what the heck??)
Look around other sites, maybe you can find it cheaper or even look at any of the name brand auto care kits, like Meguiar's etc...

Definitely pick up some good quality microfiber towels for this project. You probably don't need to buy Griot's towels for this project, but definitely get some microfiber towels to have on hand.

That kit comes with basically everything you need to do your 1.5 () cars to get them looking their best for sale....although I "think" you might need an additional clay bar...not sure...
I haven't used my kit yet as it's been too hot....but hopefully next month I can start.

So for roughly about $100/car you will get them looking their best and maybe get a little more in the sales price.
