Thats interesting... I think the ride on the runflats 18's is much worse then the ride on the e53 with 19's on. Also, the e70 FEELS smaller and lower (to me) then the e53. I dont like the I-drive at all - the interface is overly combursome. I prefer touchscreen. I also dont get the need for the fancy shift selector.

I do like the comfort seats a lot (didnt have them on the e53) and love the pano sunroof. Also like the comfort access a lot.

I did have an fx45 for a short while between the e53 and e70 and I have to say that Infiniti got the technology aspect just right. The tpm screen showed real time pressure in PSI, the nav was very well put togather with a simple interface and a readable screen (resolution on the e70 kind of sucks). I wont get into the other aspects of the the FX though...
