My father was a VW mechanic in the 70's, 80's and 90's. I've (personally) owned bugs, rabbit's, 1 1971 Camper bus, a ghia and been around so many from my dad's obsession, it makes my head spin.
I've never been into too many domestic cars (Domestic trucks I enjoy) I've mostly been a Honda, Toyota and Mazda man (I currently have 1998 Mazda MPV, 1993 Ford Ranger Pickup and the wife has a 2007 Mazda 3)
I once rented a Malibu and was completely surprised with it.... pretty good experience over all.
Here's the jist: Words from my father: "VW's are great if you like to work on cars ie: have for a hobby, because they always break down"
I will never (intentionally) own a VW again in my life. That being said, I'm not real sure I'd own a Malibu.... based on a personal disdain for domestic cars (although, I like to think they've gotten better) SO, if it's between the two - I'd go Malibu. If you can open up your options, check out hondas/mazdas.
Good luck (and I echo previous comment about buying used - much smarter!)
