There are all kinds of combos you can find for SS optioned Camaros,the most important thing to look for is what is important to you.
If you are looking for something to beat on or mod out.Don't buy an SS.If you really don't have intensions of trying to keep the car for a while,again you shouldn't get the SS.If your under the impression that the SS's have a power advantage over a Z28 and thats all your looking for...again...and SS would probably be a bad idea for you.
On the other hand if your looking for a Camaro to keep for some time or,are real into the history of Camaros.Not saying the Z28s don't have a rich heritage in Camaro history.You can't beat having an SS for collectability and the plain old history vibe you get of having one...Just my opinion.
Both the SS and Z28 are pretty much equal in the power department so,if yourlooking for straight ahead power without all the "flash and baggage",go for the Z28.
If you want a little more collectability and want to keep it mostly stock,many people including myself find the SS the perfect choice...Plus I also like the look of the appearance items which when you add them up after buying,installing and painting...it usually ends up running you aout the same amount as if you had just bought an SS in the first place...
