First Time
 Did a ton of research before deciding on this car.  Traded a 2005 Highlander and got a fantastic deal I couldn't pass up.  The only thing it doesn't have is the seat warmer, but here in Florida, not needed.  It is the I4, runs great, smooth acceleration, braking is great. Drove home from the dealership on the turnpike...doing about 75-80 mph, ride was smooth. I must admit, I have to keep an eye on the speedometer as it's hard to tell how fast you are going the ride is so smooth.  Interior design is great, very comfortable.  My Highlander was a V6. I honestly don't notice the difference in power between the two.
