RE: LATCH in 2002 VW Passat GLX - Retrofit lower anchors?
Yes, they can install them. The Passat comes without the anchors and the dealers are supposed to install them at no charge. We had to do this with our 2001.5 Passat.
I strongly suggest you get them installed. The Passat is tough to install with LATCH and even harder without (that's why we don't have it anymore). However, you can't use them in the center, as Julie said. It is very difficult to get a center install in that car, so you may need to use the outboard, in which case LATCH will make it much easier. It should have side curtain airbags, so I wouldn't worry too much about an outboard install.
