need advice engine fire / overheating
 

at robrinette.com in the guide to purchasing rx7... he writes "The car must never have overheated in any circumstance."

What are the experiences of some of you that have overheating/engine fires issues?

What can i do to check if an FD has been properly cared for and repaired for after the incident, and what signs can i look for that existing problems directly linked to the incident have not been resolved.

I've been shopping around for a FD, as a new prospective owner with not too much hands on experience. thanks for your input in advance.
