I think you are going to find the Matrix to be weak. I test drove the Vibe (w/my gf and salesperson onboard) and found it to be dog slow. You hear about the lack of low end torque, and that's to be expected. But I was at least expecting some sort of turbo rush near 6K RPMs, and it wasn't to be found. Too much work for not enough results IMHO.
Good luck.
