Keep the Blazer! Sorry, Im partial to Blazers as I own 3 of them. One of my trucks
Theres a few different types of civics, 4 doors, 2 doors, or hatchbacks. Different trim models too, EX, DX, HX... They are pretty standard, I think the differnt models just have different options, 1.6L engines, although some have VTEC, like the Civic Si models.
