I've been eyeing the new Camrys very closely myself, and I'm even thinking about stepping up to one and trading in my old Corolla. I've never owned a Camry, but both of my parents did and I've driven theirs extensively in the past. They are very well made and reliable cars. They're roomy on the inside, and very comfortable. They're also quite attractive--they look almost like a similarly styled Lexus (which might be either a selling point or a deterrent). Eventually my mom traded hers in for an Avalon and my dad now primarily drives a Tundra, but while they drove their Camrys they didn't have ANY with them. Camrys get excellent gas mileage, too. My dad's new 15 MPG Tundra frequently gets left in the driveway when he wants to conserve gas. It's on those days that he drives his Camry, which is probably a good ten or twelve years old by now.
The only thing that might keep me from actually buying a Camry is the fact that they're everywhere (I tend to want to be quite a bit different from the "crowd"). You see hundreds of them every day, from various years, because they're so well made that people can drive them forever and ever.
I've never driven a Jetta or even known anyone who owned one, so I unfortunately I don't have much to offer there. However, I think that if you ever had to have your car serviced for some reason, it would be easier and less expensive to have a Camry taken care of as opposed to a Jetta. The same goes for parts and replacement in the event something should be necessary.
Hope this helps!
