Had an suv (Nissan Murano) and a roadster (BMW Z3). I ended up not enjoying them both as much as I should with the 2 car setup, being single and all. So I decided to sell both and get the IS 250 AWD - the best combo for sportines, luxury and awd. I highly recommend you the IS 350 if you like to go FAST. I am impressed with the HP/torque of that car but decided to choose IS 250 because I want to get AWD and fully loaded with tech package. The price for a fully loaded IS 350 is way beyond $40K which a bit too much for a small sedan. Whether you choose IS 250 or 350, they are both Lexus. With stellar reliability, good looks, luxury, comfort and perfect built, you will not go wrong either way.
NAV, bluetooth, HID xenon headlight, leather, good looks of the car, reliability, resale value.
Should have another 20 HP or so to 220 HP (with the new SAE rating of course).
