We have several Vibes in our Household (4) and I know my 09 GT has ABS but I found (Surprised) that my son's 07 Base does not as I slid through the intersection this Christmas morning, icy Wisconsin roads! I was really surprised that they weren't standard, I've had ABS on cars since the late 90's but did Vibes really not go that way?
I did a spot of Googlefu and it looks like the ABS was optional in the first generation. It seems like they became standard with the second generation (but my sources are iffy so I could be wrong about that!)
Correct. In the first generation Vibe and Matrix, when looking to buy a used one, you have to look closely at whether it has ABS and/or side curtain airbags.
