E38 to E53

[imola38]

I'm currently the owner of a 2001 Imola red 740i sport with 110k miles. I'm a BMW technician at a local indy shop here in Ga. I love the E38 but I've had it for 2 years now and have always loved the X5 4.6 is's. I'm just looking for opinions, rants/ raves on the E53 with this setup. We rarely see them in the shop so I haven't had the opportunity to drive more than one.

Also, what are the differences in the IS as opposed to the standard sport besides the bored M62TU, body cladding, 20's etc.

Lastly, if anyones knows the best place to find a well maintained 4.6 IS I'd love to hear about it. Also looking for a buyer of the E38 if anyone's interested. Sorry for the unintended plug. It's my first post on the site. Thanks in advance to all who reply.
