Good Afternoon, Im 6ft and have the IS 300H Executive the seat does alter and i find the position very comfortable, i recently did 8 hrs drive and it was very comfy.I
recently had the Jag XF and although a nice car the Lexus is better, no messing with silly stop start buttons, no clacky diesels in slow moving traffic. The satnav is as good as any others I've used and the car has plenty of performance if you want it, i mainly use it in Eco mode and get 45 - 48 to gallon, if you drive it in Sport mode its fast but MPG suffers, but you can't have both performance and MPG.I
ve owned a MB E320Diesel and its as good although the sat nav is better, i would opt for a test drive over a weekend and see what you think, personally i love mine and can't see what i could change it for that would be better value for
