	Also, my trip-computer is clearly *not* to be believed. When I said
	I got only around 21-22 mpg, I was quoting actual fill-to-fill averages
	-- my trip computer consistently over-estimates by about 2 mpg.

	Well, I filled up yesterday, and I'm going to try and keep my speed
	down to around 65 and drive more sedately.  Horribly difficult
	sometimes: there's always some guy on the Richmond-San Rafael bridge
	just *asking* to be blown away :-).  Let's see what happens.

	By the way, what kind of "tune-up" could one do on these cars
	('85 5000ST)?  I've put in new (Bosch Platinum) plugs and an new
	filter (it may have been easy for some folks, but it was a real
	pain in mine ..) but I can't think of anything else that I could
	easily do.  If it ain't broke ... etc., I suppose.
