I say go for it...I'm guessing you'll begin to see light swirl marks before 2 years is up. You'd be surprised to see some new cars look worse than older cars with the great dealer prep people recieve these days
You're going to love the PC, it is a very wise investment and you won't regret it. Are you going to be picking up some polishes as well this purchase or wait until next time? If you're looking into polishes I would reccomend
Blackfire Finishing Polish (light swirls/micromarring), and Optimum Polish/Compound for moderate swirling
