Noah, that would be me.
Well, the Vibe and the WRX are in the drive, the P-car and the chopper project are in the 2-car garage.
Anyway. The Vibe is the EXACT same vehicle as the Matrix except for cosmetics.
They are both built at the NUMI plant in Fremont, CA. Platform is the Corolla.
My recommendation is to find a dealer (Pontiac or Toyota) that you trust and buy from them. Be sure the service folks are the ones you trust--you'll never have to deal with the sales staff after the purchase.
