there were some 5 million E46s made in their run and if when a cooling part broke in any of these according to you each of them would have a catastrophic failure. this is not the case! people turn the engine off in a timely manner when either one of up to three gauges/lights activate allerting the driver to pull over and shut down. or they can see steam or feel the belt not driving the ps.

sure the aluminum head is sensitive when over heated but this is nothing like when a timing belt breaks.
the process in which the engine destroys it self isn't the same, sure, but the end result is often the same: destruction.

Out of the five million E46s you state exist, a very very very VERY tiny percentage of those owners are "car people." an even smaller percentage are enthusiasts. and even if you DO know your E46 information/engine schematics backwards, forwards, up and down, that still doesn't guarantee you're always staring at your gauge and it certainly doesn't guarantee you'll be in a position to pull over and get your car towed. Think about how many situations you could be in where pulling over and/or towing isn't an option. It's better to spend a little now to prevent the headaches of having to tow (often times costing half, the same, or even more than an entire cooling system overhaul).

sometimes its nice to just drive a car with confidence.

the pros of replacing it all greatly outweigh the cons. the only con is you spend $500-720. but really, for a car that costs $7,000-$12,000 used, that's a small price to pay for a responsible working adult to have reliable transportation.
