Is the 2005 Mazda RX8 worth the purchase


Asked by Jul 04, 2016 at 12:38 AM about the 2005 Mazda RX-8

Question type: Maintenance & Repair

I am thinking about getting a used 2005 Mazda RX8.  I wanted to know how much
it costs to maintain and I would like to know from someone who owns one if the
maintenance is worth it.  Additionally,  I know someone who would sell me one for
$2000 but the engine overheats because the exhaust is blowing into the cooling
system.  Is this an easy fix?  The car only has 80,000 miles on it so would it be
worth the purchase?

I'm not an owner but maintaining it would be like any other 11 year old car. But in the Mazda they use a rotary engine which as many issues. but from the sounds of it, the car you are looking at has issues. It is not an easy fix, requiring cooling system and engine work. You can run into a few thousand getting it repaired. If money is tight, I would pass.


First of all don't buy a rotary if you don't know anything about them, I use to race these little engine in my younger years, so here's they low down. If your getting exhaust into the cooling system then the motor is blown, a rotary is way different than a piston engine, when that happens it just a matter of pulling the head having it pressure checked and shaved then put it back on, on a rotary the engine has too be pulled then taken apart and inspected if the housings are warped they must be replaced, I know some guys have just had them surfaced and they lasted about 12k but that is short cutting it, then there is also the damage the coolant can do to the sensors and catalytic converters that you might have to deal with if it has ran too long that way. So it is not an easy fix, more likely you will replace the engine cause a lot of places won't tear down a rotary. So if you decide to take on this project the mantance costs are fairly high, just due to the fact that these are two stroke engines and do burn oil from the crankcase so oil changes are frequent and cannot be something you can let go plus you have to keep checking the oil daily to keep it topped off, cooling systems are another area of concern, they must be maintained, good hoses, thermostat, coolant at all times, I could keep going on but I think you get the idea. As far as the price that seems way too high for something with a blown engine and 11 years old, what few rotaries we have around my area with engine problems are going from 500 to a grand depending on the condition of the car, ther was one that was really nice that sold for 1500 that the engine was blown on, I was going to buy it myself but someone beat me to it. Hope this hasn't bored you and gave you some knowledge.
