Miata update: I had a very enjoyable late summer & autumn with this car, putting maybe a couple thousand kilometers on it.
The only problem I had was the water pump started leaking right at the end, in late October, so I parked it. Next summer I'll replace that plus do the timing belt.
Of course, knowing me, you won't be surprised that I also started modifying it to improve its fuel economy. My last tank was 4.7 L/100 km (100% relaxed top-down cruising on the scenic roads).
