I have owned by IS 250 since October, 2005 and have 11,000 miles on the odometer. The vehicle has undergone the following repairs in addition to routine maintenance: 1. Reinstallation of leaking dip stick tube. 2. Replacement of seat belts as per manufacturer's recall due to lock up. The best gas mileage I have experienced is 36 mpg on a trip where the average speed was 50 mph. At 70 mph the average mileage is 32 mpg. In town I am averaging 26 mpg.
Good gas mileage and comfort of vehicle interior. Vehicle has also been reliable so far. Modest highway performance is acceptable when balanced by good gas mileage and comfort
Re-design engine to run on synthetic oil requiring fewer oil changes. Improve side mirrors to increase rear view since rear fenders are impossible to see. Increase rear seat room.
