Ok I can answer my own question. A1, full up with family 5 on board off to wedding. Van in front, the two cars in front of him collided, van slammed on, just missing the accident. I ended up about 4" from the van. The car braked before I did. So yes, it works and is awesome. It saved the car and the family from a shunt. I've done about 3K miles now and would say you would have a hard job getting me into a daily (long distance) work driver without radar cruise. You have to learn how to drive with it but it it just brilliant when you have 200 miles to go late on friday night tired on the way home. The D4 has really found a place in our hearts. And as for the family wagon R320 Mercedes it has a persistent battery drain issue. Which is intermittent. The wife would rather I sold it to a couple of "travelling gentlemen" who put a lowball cash offer on it a few weeks back before its latest round of failures. I laughed then, at their offer. I'm feeling kind of remorseful now as it's about to go to we buy any car or the auctions because SHE says it needs to go NOW. (I concur). All of this means we have our D2 S8 back on the road as a classic car. Taking the place of the R-wagon for pottering about while I'm away. A D4 4.2D and a D2 S8 make a formidable pair. Both of which put the extraordinarily bad engineering (playdoh engineering) of the merc into context. I has a 1983 S class and it was epic for may reasons. This R-Class is an embarrassing (and expensive) legacy. good riddance. Anyone want to by an R-class?
