1987 Porsche 911 — costs that mattered more than fuel economy — buyer question from Nashville

If it were in my driveway, a pressure test beats staring at a dry driveway if the 1987 Porsche 911 is losing coolant with no puddle. That's the branch I'd chase this week. Keep sale price, fees, and rate as three different conversations. That's my plan before I call anyone.

Intermittent stuff lies if you only catch it once. Capture voltage while the 1987 Porsche 911 is actually failing — after it restarts you've lost the clue. If the cheap test changes it, stop and reassess. On “costs that mattered more than fuel economy,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. Climate here is different, so treat that as a local data point. If it repeats twice more I'll book time.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 1987 Porsche 911 and see if the fault moves. That's the branch I'd chase this week. If it doesn't change the out-the-door or the repair estimate, it's noise. If it repeats twice more I'll book time.
