We get a lot of opinions here, people with good luck or good results independent of luck, and some with terrible results. The variable that many don't consider or we talk about much is that many owners RARELY drive their cars, and often for very few miles. Cars that are not driven may have all sorts of issues that are slow to reveal themselves.

Cars that get driven frequently and for some distance may not have problems from issues that cause problems in less frequently driven cars. Specifically I am thinking about coolant damage, which usually shows up around the water pump and/or the head gaskets. Of the dozen or so engines I've seen torn down that have sat for any real length of time, 90% had moderate to serious damage. It looks almost like a termite with an 1/8 inch or so track that may wander over the surface under the gasket, or some kind of serious cavity.

Seems that once coolant gets under the gasket it goes bad fairly quickly and eats the aluminum, which allows more coolant in, repeat until junk.

Whether or not this presents a practical problem may depend on just how much its driven, and how long its parked and what type of coolant is used.
