Well having owned an IS300h F-sport 2015 with only 18k on the clock for the last 8 months I cant say I was impressed with the MPG.
Just returned from a round trip of 296 motorway miles and reading 39.2 MPG. today
The best I have ever achieved with it is 41.2mpg and that was trying very hard to get the most MPG out of it.
Quite disappointing really!
Lexus is300h f-sport is a great car but I don't believe the MPG claimed is achievable in the real world by a long stretch.
MPG is not the main factor for getting rid of it though, I just don't find the car very engaging to drive but its been nice to try one.
Pick up a new car on Friday .
