I have no comment about the low temp thermostat, I am still waiting on the vacuum fill tool I ordered to get it running again.
I have not been daily driving the Box recently as I switched to commuting on my motorcycle most days. However I do believe in driving the wheels off of anything I own. So 88K is just getting started.....
I do also believe in a mix of PM and RM. Served me well so far.
Also the 987 is my snow toy. So much fun hitting twisties in 3" of un-plowed snow. But I'm lucky in not having salt on the roads around here.
The coolant that came out was also the cleanest and best looking of any car I've drained. That made me feel good too.
