This is my second Vibe---my first is an '03 with 103K miles which my teenage son will inherit. The '03 has been flawlessly reliable! I purchased the '09 last week at an incredible deal--$4300 off in GM/Driver's Edge card rebates, $3000 in additional rebates for paying cash, and at a price that was well below invoice!! I was a little concerned that Pontiac parts might not be available in the long haul but GM insures me that Vibe owners will be supported for years to come. Since the power train is Toyota I am not concerned. If you are shopping for a reliable vehicle that gets great mpg--Vibe is the way to go.
Mpg, storage capacity, reliability, handling in snowy conditions, and general design.
I would have liked availability of the 4-speed transmission in the 1.8L version. The 1.8L '03 had a 3-speed w/overdrive.
