Mazda RX8 is it worth it?
 

I'm looking at purchasing a new car and I came across this one. If you don't want to click on the link it says "It smokes a little when driving."

My question is what could this be from? I'm thinking about getting it if its an easy fix but if its going to cost me a lot I wont. thanks!

Just a guess; apex seals. It's an easy fix if you think an engine overhaul is easy. :p
