Go to
www.zainobros.com and print out an order form. Next, I would order Z1 Polish Lok, Z2 Show Car Polish, Z5 Swirl and scratch remover, Z6 Gloss Enhancer, Z7 Car Wash and some applicators. If your car has some miles on it, I would go ahead and get the clay bars too.
I bought all of these and the leather cleaner and conditioner and spent just over $100. I am just about to run out of the car wash. Other than that, it will last you quite a while. The Polish Lok you use initially but want use it again for a while. The Z2 and Z5 will do the whole car about 15 times, although you won't use the Z5 as often.
