Link to June 5 Mashable post, "MotorMouths is the Rotten Tomatoes of Car Reviews".
Great "consumer" link for library webpages. Most of the reviews for the Toyota Matrix, for example, mirror my generally happy, 3-year experience with this vehicle.
Not mentioned in the summary reviews: the superb comfort of the driver's seat -- particularly for someone with a recent history of back problems. (Like me.) And the car is very easy to enter and exit, unlike the Saturn I drove from 1996 to 2006. (Another important consideration as Retiring Guy finds his body isn't as "springy" as it used to be.)
