Yeah, didn't mean to start a 4.6 (driven a very nice 4.6 on many occasions) vs. 4.8 debate. Sorry again. I like both vehicles a great deal... am just trying to figure out which one I want to plunk money down on (and into).
I understand why some would not want air on all corners... but I do even with the increased maintenance costs. Adjustable ride height is worth it for me. 6spd vs 5spd is great since it turns terrible gas mileage into slightly less terrible gas mileage... LOL. And engine maintenance issues are the same in my eyes as the labor/cost to do chain guides on the m62 is about the same as doing the valve stem seals on the N62 (if not pulling the head). That's actually when I drove the the 4.6, after it had new chain guides and chain after it came into the shop I was working at. Very nice vehicle, owner of the shop liked it so much he tried to buy it from the customer.
