I love mine! I'll be an H2 owner as long as they continue to make them. BTW, this thread is sure to bring out all the "H2 haters" so don't listen to the crap spewing from their keyboards. They probably drive Ford Pintos and have never even rode in an H2. I've yet to hear an owner (or previous owner) of an H2 have any major complaints with it.
Anyway, to answer your questions.
- They are very comfortable, especially for long range trips.
- As far as the top speed, I couldn't tell you. I don't think people really buy H2's for street racing.
- Overtaking other cars isn't a problem considering the 316HP 6 Liter V8.
- Definitely no excessive noise for an SUV.
