I'm thinking about buying an RX-8 and I test drove a 2005 6speed manual Rx-8 sport, it has 65k miles on it.

I had a couple of concerns, but maybe they are normal with a rotary...

1. blue smoke from exhaust, suggests burning of excess oil maybe a compromised seal on a normal engine.

2. when it was in idle RPMs went from ~0-1000 then back down until the gas was pressed down then it idled fine.

3. a lot of oil odor after the initial startup and idle smelled similar to a leaf blower's exhaust.

It's from a dealership and they are asking 10k, i'm going to ask for a compression test log, but will they be honest is the question.

If anyone can provide me with a little insight on these cars and my questions that would be great.

 

Does it have a cat? Catless car smells like a catless two stroke engine (lawnmower).

Get the car tested at another dealer...However, does sound like trouble...

 

Walk away. Read the second thread linked in my signature.

 

That car has issues, find another one, good luck.

 

pick a different one.
