I recently purchased an 85 300td and am in love with the car. The only thing it lacks is the third seat (rear-facing in the back). The dealer told me that I would be able to add it even though there has never been one installed in this particular car. I found one (online, so I can't physically look at it) that has been removed from a 1984 300td. Do any of you know if this will fit in my car, and/or if I really will be able to just bolt it in and install the belts somehow? Thanks for any info, Hannah
