It's okay to buy consumables like oil, filters, plugs and the like from any random discount chain. Prestone is Prestone, Champion is Champion, and so on. But when it comes to hard parts don't even slow down on the way past that discount chain outfit unless you're a broke-*** mufker who's just limping the vehicle along until your grandma dies and leaves you her Buick. And she's not going to leave you her Buick anyway. She's already explained to her friends that you'd not appreciate the gift because you're a loser who doesn't take care of what he's already got so she's donating her car to her church.

You don't want buy crappy parts and make yourself into this guy:
