Everyone I've ever met who has had P600's or P6000's on their car has not been happy with them. Everything from lousy mileage, sub-touring tire ride, noise (most common gripe), etc. I'll second Steve's opinion....you really can't do better than Michelin. For touring the Energy MXV4 Plus is as good as it gets. If you want to crank up the handling that opens up a pandora's box of other options and tradeoffs but for what the car was designed for, you will be more than happy with the Energy MXV4 Plus.
Hope this helps...Lee
