This is what my maintenance has looked like over the last 2 or so years. I kept a log and I figured some of it may be pertinent information for Zpost users. You can also post your logs or maintenance on here.

I'd say I've spent roughly around $2500 over the course of 4 years of ownership (this thread covers 2 of those years, prior to that there wasn't anything done except regular maintenance). The car currently runs like new. I had a serious MPG problem that was solved either by the fuel filter or by the spark plugs. I don't have the readings yet but with a bit less than half a tank I already have more miles on this fill than prior
. And yet after all this I still have a somewhat unsteady idle.
Update Jan 2015:
-MPG is definitely back to normal standards
-Driving in winter with blizzaks, love my car.
