My wife and I bought an '06 Matrix XR in late March. We liked it so much, we bought a second one a week ago. We have three Collies and the Matrix is ideal for transporting them ... room to spare with the rear seats down. We really cannot think of anything we don't like about the Matrix. I've seen comments about cheap interior, but it all looks fine to me. Everything fits and there are no sqeaks or rattles. My wife and I both feel that they are not noisy at highway speeds. They also seem to have more than adequate acceleration. Fuel economy falls right in line with the EPA estimates. I'd recommend this vehicle to anyone looking for a small versatile vehicle.
Fuel economy ... mine falls right in the EPA estimate. Ergonomics. Versatility. Interior room. Versatility.
A little more horse power would be nice but not really necessary. Visibility could be improved, but can be compensated for as is. Just nit-picking here.
