I chose the IS250 over BMW 3 series and Audi due to superior interior fit and trim. Lexus interior finish is by far higher end than BMW finish at a more affordable price point. Obviously the 250 could use some more power, but you can get that in 350 and the 250 gets great mpg. Combined hwy and cty mileage averages about 26mpg. I get 31mpg on hwy. The audio and nav system is superb. One drawback is not being able to program the nav system while the vehicle is moving. Bluetooth is clear. Dashboard instrumentation layout is very sporty and provides quick reference for temp, tire pressure, mpg and distance to empty. Paddle shifters are nice touch and add some sportiness to daily drive.
Air conditioned seats... live in AZ. Paddle shifters. High quality interior. Very quiet ride from tires and cabin is very quiet. Sound system is terrific. Exterior styling is superb. Great gas mileage.
