I change vehicles every 2-3 years due to the amount of miles I drive. I have owned 2 Lexus (Lexi), 2 Audis and others. This is my favorite vehicle ever. I opted for the 4 cyl. to get the better gas mileage. I am getting 29 miles on the highway and 23 miles city. Incredible for a vehicle this size. I test drove the 4 cyl and the 6 cyl and bought the 4 cyl. Brought the salesman with me for the extra weight in the vehicle. We both weighed about 200 lbs. I didn't notice a considerable difference in power or acceleration. Others stated problems with seat comfort, fit and finish, yet I have 100% satisfaction. I love it. Everything I paid $27.733 for the LS with most all options.
