When shopping for an SDL, I'm just wondering how I can gauge the potential that a car might have (or will have) a cracked head? Is it an age related thing, a frequency-of-coolant-change thing, or is it just totally random? Was the head cracking something that happened early on in the cars life and would be fixed by now (i.e., random heads were cast poorly, or had some other manufacturing defect)?

It seems to me that a lot of people "have heard" that these cars can crack heads, but I have only heard ONE person on this board say that they have personally experienced the problem.

Lastly, do these cars have the B2 piston issue, or was that only on the gas V8s? Are the transmission in these cars as good as those put in the w123 300D?

Thanks,

Greg
