X5M vs. 4.8is questions

[jigaro]

All the M owners

Hey guys just wondering couple of things

I had a 2005 4.8is and now i have 08 4.8i

I find that the ride of my 4.8is was much better than my 08 model, in general going over the bumps it was quiter and let's say it was better put together, maybe it's my 215's with runflats. so question is.

How does the ride of M compair to 4.8is and E70 in general? Is it smoother? rougher? Going over the bumps, any ruttles and such?

Also, the exhaust note on my 4.8is was amazing, but my 08 4.8i does not sound that impressive at all, i know this has been discussed quit a lot but, you guys the new owners of X5M, are you happy with the exhaust note? Does it sound better than 4.8is?

Thanks in advance, and i will be eventually getting the M sooner or later, and just wanna have a general idea as to how the m compairs to my previous 4.8is, because i know my E70 does not impress me at all at the moment.
