yaaa i get what your saying. most people think that but any chassis part from the grand am will bolt straight up to my car. it's the same car but a different body.
the 2002 alero was the first gm model to have the ecotec in it so any cobalt, cavalier, sunfire, etc engine mod will bolt straight up.
i have like 3 pages of written mods down on paper that are possible for the ride ha. more research than the car is worth but it'll be cool in the end. especially to not worry about having another bad ass alero roll up next to me ha
