Real MPG: Lexus IS (2005 - 2013)
Very well built. Top quality interior. Lexus dealers are best in the business. Impressive refinement. All engines chain cam. IS250 probably the most reliable car you can buy.
Poor change of manual gearbox is not suited to V6 petrol engine. IS250 thirsty. Ride and handling lag behind C-Class, 3 Series and A4. Rear seats don't fold.
