Differences of 4.8is years 2007-2009

[shebuilt]

It appears my 4.6is may be taking it's toll on me needing repairs at this unrelenting time of international travel leaving me little time to perform the work myself.

Interest from those current and previous owners about the differences between 2007-2009 4.8is.

I'll be purchasing one soon enough and wonder what to look and look out for?

Much appreciated!

Theres no such thing as a 4.8is 2007-2009. If you talking about the E70 4.8i, the difference is 2 completely different cars, including different motors (although both are 4.8 n62s).

Just added the is in error since I currently own one. I am referring to the 4.8i E70
