I am going to have to agree with Mike, something is wrong with this. Either something is really wrong with the IS-F or someone is trying to scam you. Your RX7 is cool but like Mike said its only worth about 15k TOPS. So unless the IS-F has 60-75k on the clock, paint was never taken care of and leather seats show signs of wear, thats about the only way I can see someone wanting to do this trade.
