Well, the old 2.0 has been an awesome little winter beater so far... still planning on a VR6 swap in the spring, however.
I'm definitely getting kinda attached to this one.
Anyhow, the passenger side rocker panel had a bunch of lumps on it, and when I poked a bit, I ended up with a 2 foot hole in the rocker. From what I can tell, the car was in an accident, and a body shop just ground the dented portion of the rocker down to bare metal, and covered it in Bondo... which absorbed about a gallon of water. This thing was ROTTEN! I ordered a new rocker panel from VW and installed it today.
I had to be a bit creative welding it back in, as the spot welds along the upper seam appear to be done while the car is in several pieces (ie, the sides of the car aren't attached to the roof and floorpan), but I'm very pleased with the way it turned out.
