I had an 04 xb, now an 08.. here is the comparison pros and cons
Pros
WAY WAY WAY more power and torque
More comfy, more room, Im 6'3
Much easier to read gauge panel
Feels more stable, like a real car vs. a toy
Cabin is quieter
More fun to drive
Cons
Big difference in gas mileage
Harder to find parking spaces in the city
Kinda liked the go-kart feel of the old B
Aftermarket parts cost more, less availability
