Quad, Great idea for a thread.
The 5 gets a 7. I like the way handles and was surprised at how refined it is, particularly on the highway. The size and functionality compromise is perfect as it has a small footprint for easy maneuverability yet is large enough to actually carry stuff. And as much as I didn't appreciate it having two sliding doors for hauling around a 3 year old and a 1 year is very, very nice. That it hasn't had any unscheduled maintenance in the 40,000 km we've owned it (55k - 95k) gets it the the extra point for a seven.
It gets docked points for being both underpowered and not good on gas. 3400 lbs is just too much weight for the 2.3 I4. If this car could easily get in the low 7's on the highway and had an extra 50 hp it would likely be a 9. The extra point would be earned by having a hydraulic power steering pump and a slightly faster steering ratio. Surprisingly, steering feel is one of my big gripes about this Mazda.
The Protege5 was probably an 8.5-9.0. I love that car. It lacks a TON of refinement, particularly on the highway, but it makes full use of it's 130 hp and it never met a corner it didn't goad you into tackling with gusto. Practicality and good looks are a bonus.
