Good lord man... Too many things I want to resond to, but I don't want to really care about this...In no particular order:
-How can you say the car's history is perfectly legit if it's got some type of modification to the odometer, and a WARRANTY VOIDING intake? Chances are, it had more mods that were removed before it was traded in.
-You are willing to pay thousand's more for a car to get an absolutely HORRIBLE warranty on a car that is probably not even under warranty anymore. Trust me, when you bring it back for a warrenty issue, Mazda will investigate the odometer swap and all of a sudden they'll tell you the REAL mileage.
-**Bump for my own sale** I will drive my car to you and fly home, and you'd get a car that is probably as clean in stock form, and way better looking with the mods I have. I'd even sell it cheaper than what you are going to pay. I probably have $6K in mods alone.
-Don't try to convince yourself that it's the only Mazdaspeed, and it's one of a kind. (attn) I have one EXACTLY like it, but cleaner, faster, and cheaper.
-The warranty is overrated. I've got over 63,000 hard-driven, redline pushing, 11psi boosting miles and the only engine problem I had was a faulty thermostat that I changed myself at 32,000 miles.
-More than likely you will still buy this car, even though I think everyone here is telling you (from experiences we've had) that this car is not worth anything close to 18K, and honestly, it's a bit suspect even for $15K...
