DOH!! Sorry. I'm forever missing details, such as your tag line, on web pages.
It truly is hard teaching "old dogs" new tricks. Might have something to with the fact that I was born more than 25 years before our cars rolled off the assembly line.
I have the same car except an auto trans. 7/10 sounds pretty nice. Mine is nowhere near that condition (worse), but has about 10k less miles.
I recently noticed the dread coolant odor in the passenger compartment. Tried a little stop leak and it went away. Gonna "thank my lucky stars" and leave it alone.....for now.
FWIW, mine didn't need a flush and fill. The radiator fluid mix looked new and maxed out on the hydrometer. T-stat seems to be doing its job, as well.
Best of luck with yours. I'll be interested to follow along.
