I really like my CX5 Touring, now at ~ 65,000 miles and was comparing the Turbo version with the RDX and other turbos vehicles. I was surprised that most suggest the first Tune-up at 100,000 miles for spark plugs while MAZDA is at 40,000 miles. Since most drivers will have the plugs changed instead of DIY, that will be a sore point. I'm courous if MAZDA will reevaluate this after they get some additional driver data? Ed
