I'd definitely go for an F Sport, the improved spec is worth it for sure... I just have myself and should be picking it up on Saturday!
Had a couple IS200's and an IS250, but replacing a BMW 320D coupe that I bought after a write-off. Can't wait to get back into a Lexus, never had a single issue with any of them, but not been the same with the BMW!
It's a 63 plate in Ultra Blue with red leather and premium navigation, little under 22k on the clock...
