Haha. How about some advice from someone that actually owns one. :grinno:
I've owned one for about 18 months now (35,000 miles). I have not had 1 problem.
First off, oil consumption. Its not a big deal. Check your oil level once every 3 or 4 gas tanks. I change my oil every 2000 miles, and over those 2000 miles, I'll average about 1/2 quart of oil burned....so I never need to top off my oil level. Still check it though just to be safe. Adding oil is not a PITA, its right there on top just like any other car. If you drive it like a race car, it'll burn more so check it more often. Don't be afraid to open it up and let it run...rotary's love it.
Gas consumption: Highway driving expect to get 20-22 mpg, in town around 17-18 mpg. Its a sports car, not an economy car. It burns gas.
Recall: All 04's and 05's were recalled. Some ECU's were not operating the OMP (oil metering pump) correctly, therefore not injecting oil (or not enough oil) in the combustion chambers. The seals would dry out and the engine would lose compression and eventually wear out. Less than a half percent of RX8's had these problems. Most of them were 04 Automatic Transmission models. That year the auto's only had 1 oil cooler and that was the problem. All manual transmission models had 2 oil coolers the whole time. All auto's after 04 have two oil coolers as well.
Mine did not come with extra plugs. I short drive mine sometimes too (less than a mile), and never had any problems with flooding or fouling plugs. Just rev the engine right before you shut it off and you'll be fine. Plugs dont last long though...about 35,000 miles. They are easy to replace.
Things you probably wont like/quirks: Make sure your's is not part of the recall. Its all done for free, and they remap the ECU, check the cat, and vacuum test. Like I said, it was something like .5% of cars that had problems...most of those being 04 AT's.
Rear Hubs will rust slightly after a year or so. I painted mine black with caliper paint. Works great.
About all I can think of. If you want to know anything else, just let me know.
