is the RX-8 a pain in the ass and expensive to maintain? (reg. scheduled maintenance, parts breaking/wearing easily [mounts, struts, bushings, etc])
can i drive the RX-8 with confidence, not worrying whats going to go wrong next?
how well does the RX-8 respond to modifications, and other than the engine internals, is it fairly easy to work on without the need of a mechanic?
Oh, last thing, this engine flooding issue... I have read some people never had it happen, some people have often, some just do a few things to overcome it... is it all just simply allowing the car adequate time to warm up and down before shutting off?
Of course, our '06 GT doesn't have enough miles on it to say much about the maintenance, other than oil changes. I'd say the RX-8 is no worse than the other Mazdas. Mazdas, in general, have a pretty good maintenance track record. Granted, the RX-8 has had it's problems; but, I think most were sorted out by the time the '06 GTs came out. I just check the oil and tires, on a regular basis. If I felt the car had really bad problems, I would never have bought one, even if my wife likes them.
When it came time to drive almost 800 miles to VA to pick up my Miata, we picked the RX-8 for the trip. It was flawless. As miles add up, we may have problems; but, we've not had any, other than a broken visor, yet. It fires up, every time, and goes. My wife loves driving it. My biggest concern is the core of the engine. For that, you have the 98K core warranty. Of course, gas mileage on premium sucks. If you do long distance driving, keep that in mind.
I can't answer to the mods question because we never do mods to our cars. I'm more concerned about how easily it is for our local mechanic to work on, when the warranty runs out. By then, we may not own it. We like the smell of a new car, from time to time. We can do a lot of driving without worrying about it, in the meantime.
As for the flooding, our Mazda dealer's service manager said the worst time for it to happen is when someone backs the car out of the garage to wash it. I guess it never has time to warm up and is in the high fuel mix stage that can flood it, at times. I've done about everything wrong and have yet to have it fail to start. If it fails, I'll just follow the directions on the card. I made sure my wife knows where the card is, as well. When I took my wife's new RX-8 in for some service work, just after we bought it, another RX-8 was being hauled in on a rollback truck. He said it was most likely flooded. For sure, it still had water droplets on the car. Most likely, it was being washed when it failed. Several things were changed, including the plugs, before the '06 RX-8 was introduced. Well, the plugs may have come later. Mine did get the new ones, I think, as part of the sales prep. That could be the clue to its starting without failure. I just know it's been a nonevent for us.
Trust me, I had many questions when I bought my wife's RX-8. I've watched the rotary cars since I was a young fellow in the '70s. I've always been leery of them because of their track records. The more I read, the more I think a lot of it has to do with the way they're driven. You need to wind them out, a little, to prevent the carbon. On the other hand, I also think that overdoing the winding out can bring on failure, as with any other engine. Normal driving at highway speeds should keep them running well. There are just too many RX-7s out there getting well over 100K miles on them without engine failures for failures to be the norm. RX-8s should be doing better, by now.
