Hi everyone, Yesterday I went to look at a potential T3 Caravelle. I took a torch with me to inspect it and noted a few sections of rust that I think are a cause for concern but am not sure if its a common T3 thing or something I should be worried about. This particular van is an 85 with the big sunroof in the middle. I has developed rust in the edge of the first raised hump on the roof. The rust spot is about 4 cm long and 1 cm wide and has breached the paint and is perforated. The seller has painted/treated the section and covered it with a 3M adhesive film product. That in itself isnt the cause for the worry. The cause for the worry is that not far but inline with the roof rust is a small section about 3mm blistering in the b pillar where it meets the roof gutter. Then further down inline where the sunroof drains are the sill is a bit rough looking and definitely isnt clean steel despite being painted over. I have the concern that the sunroof drains are blocked and have been for sometime causing water to fill the b pillar with water and therefore causing it to rust from the inside out. Apart from those sections the rest looks pretty much like common affair with some rust in the rear most roof gutters, a small amount in the rear lower sills near the seams and some other small spots near the windscreen. I dont plan on keeping this van for an extended period of time but also am not keen to buy something that will need to be fully stripped to repair in short order. I wouldnt have a problem with cutting out the roof section and welding in a patch but am concerned I may cut it open only to find a completely rotted out b pillar underneath. So my question to you T3 bunch, how much is too much rust and should I keep looking for a potential candidate or is this amount of rust if managed no cause for concern?
