I wasn't expecting much for power but I also have a 2002 Mazda MPV (V6) minivan and it pulls much harder than the VX I test drove so something is definitely wrong. I never really paid attention if the check engine was on before I started it but I'll definitely look into it. I found another one in my area and I"ll test drive it soon. For a VX in a condition like this they were asking for $13,500 but I think its worth $8,000 OTD. Is my price reasonable?
