I bought a 2010 Matrix 5 speed manual base model at the beginning of 2010. This is a functional car that is very average. I found a few significant drawbacks too, primarily in poor design and build but also in very poor visibility. I think there are better cars available in this category and wouldn't buy the Matrix again.
PROS: roomy interior, great fuel economy, reasonable cost
CONS: very poor visibility(huge pillars, small raised rear window), water drips from roof onto seats when doors open, cheap interior feel, doors sound 'tinny', matte finish dashboard collects scuffs when you touch it and has rough seams, clunky manual transmission and hard to shift into reverse
