thinking of a new H3, need help

Hi all, i am new to this forum, but i have been reading all the posts for the past 3 weeks

Im thinking of purchasing a H3, I have been driving German cars for the past 13 years,
So in a sense GM has done a great job lately, because never had i considered a GM car
before, but I love the hummer styling, and also love the price because... the BMW X5 body style,
is changing in 1 year and half, and it also costs like $44,000 with everything i want, there
some issues I want to ask:

1. Top speed on a h3 is 97mph? wow, i do 90 all the time in my mercedes,
took it up to 140mph, and it feels smooth, how do you guys feel about the 97mph limit?

2. H3 is bigger than the BMW X3?, from my perspective, and the hummer has more attitude!
(am I right? wow, never thought that another SUV would have more personality than a BMW, seriously)

3. IS navigation finally here, also a DVD entertainment system for the rear? are there any pictures?

4. How come the H3 rear suspension is different than the front? is that a plus or negative?

5. Also are the rumors true that the H3 will have a turbo/supercharged option, if so when?

Thanks, ive been doing a lot of research lately, going crazy about which car to buy, im selling my
mercedes c240 2001, and it feels kinda strange going to an american car, i dont mean to offend anybody,
but i love german engineering, but the H3 looks awesome, better than anything the germans have to offer,
for the price (i think the h3 with everything i want would be around $36,000)

Thanks!
