It's simpler than a carb Alan! With fewer moving parts it is inherently more reliable, those who condemn it as unreliable generally have no concept of how it works and the reason their car has broken down is because they've been meddling in things they shouldn't.

As previously mentioned, adding it to your 240 would be fairly easy and it was after all designed, as was the L-Jetronic as being a retrofit system by Bosch meaning it can easily be fitted to cars that didn't have it.

Also there is a much more prosaic reason that you don't see so many carb bits advertised - there aren't that many cars around now with carbs and those that are, generally have a generic set of spares - the market has already been cornered on these by the "big boys" and not many people these days know what does what in a carb.
