Jeff - sounds like a fun decision that you are trying to make.

After 3 months with my H3 here are some of my observations related to your questions:

-H3 windows and high beltline are cool and have minimal impact on visibility, you don't feel like you are driving in a fish bowl, feels sporty instead.
-H3 high and small back window does make backing up difficult. Depend on the large side mirrors and use caution.
-H3 steering ratio, heft, feel, precision and highway tracking is very good (my other cars are Porsche Boxster S and Jag X-type for comparison).
-H3 road manners are surprisingly good, quiet, smooth ride, reasonably flat cornering
-H3 interior space is only so-so (resulting from chop-top styling, relatively compact body, etc.)
-H3 cargo space is only so-so with back seat up
-H3 Front seat comfort is very good, rear seat comfort is only fair-to-good (and really only for 2)
-H3 fake hood vent is lame
-H3 throttle response is fair, torque band is broad, horsepower is a bit light (although the LR3 V6 horsepower to weight ratio must be even worse). How did the V6 LR3 feel? LR3 must weigh well over 5000 lbs.
-H3 is mechanically simpler than the LR3 and it's proving to be very reliable and well-built so far for me at 6000 miles.

My wife and I prefer the H3 over the LR3, even though I have access to Z-plan pricing on Land Rovers/Fords/Jags because my father is retired Ford exployee.


Just my 2 cents, hope it helps a little.
