I probably would have gone for the diesel in terms of MPG, but it didn't come in an auto! No idea why, but that put the final nail in the coffin!
I mean the auto box is excellent! Maybe I'm getting old? But I just couldn't do without an auto now especially one as great as the Lexus one.
Also find the petrol version alot quieter! The lexus diesel I found quite nosiy too, compared to the Merc (auto) diesel that I had before. Also fancied a change from a diesel this time, so much smoother with the petrol engine. Just my tuppence worth....
ps: Never noticed the ride height difference before, but another reason to go with the 250!
