compression, full diagnostic and full boost pattern test. After that decide how much its beat up on and make the best offer. If none of the prior tests come out good, DO NOT BUY IT.

if the turbos have significant play and/or leaking oil then they could be bad. That is gonna cost any where from 900.00 t0 3000.00 depending on what you do. Get the boost pattern test done on it. Hook up a boost gauge to the UIM nipple and run it in the car and courtesy of Robinette's
if that checks out then you have a healthy boost pattern at least. Compression is the other major important thing to know. Good Luck
Drive to third gear with normal acceleration
Accelerate from 35 MPH at WOT until passing 4500 rpm
A slight and smooth increase in power should be felt at approximately 4500 rpm. This will be about 65 MPH.
Boost should be above 10 psi up to 4500 rpm. The boost will drop to about 8 psi just after 4500 rpm, and will begin rising towards maximum boost depending on the length of time the throttle is held wide open. As a benchmark, many owners were asked to time their cars from 40 to 70 MPH in 3rd gear. To try the test yourself, simply cruise at 35 MPH in 3rd, floor it and start timing when you pass 40. On average, a stock car should do it in about 4.9 seconds and a slightly modified car can bring it down to the 4.2 second range.

rev it up a couple of time to the limiter if it does not blow buy it
see if it start right away
if you need to crank it up alot mean it need more compression
take for a spin se if the ball joints are good
and car fax

Listen to what he says. If you did your homework, you should have done this already. If not, I don't know what you were reading, but it sure wasn't the "Buyer's Guide for Used RX-7s" clearly outlined on several pages linked to in the 3rd gen FAQ sticky...

I would shop around don't buy the first one you look at. Plus, do what has been suggested above.
The first one might be the one you buy, but I have always looked at several before making a decision. That's me though.

The stock twins you really can't hear anything if it has the stock pre-cat on and the stock airbox. Once you get the airbox off and get a downpipe you'll hear them and even then it's not that loud.

it should be 10-8-10? if its not you got other problems. One of a hundred. You shoud have this car looked at by an experienced rotary mechanic, they will tell you right away. If you buy the car without doing this, then you bought at your own risk. Which is not a good practice BTW. DO it, you won't be sorry. Call tommorrow, find one, arrange for the guy to take it there before you buy. Pay for it yourself and get the piece of mind. If he refuses, then you just saved yourself. Be smart is my advice.
