I'm currently looking into buying a AWD sport20 here in Japan for like 1800 American dollars. My plan is to drive it for the 2 years I have left here and then strip all the parts off of it and send everything back to the states to mod my P5 there with the JDM stuff and the AWD system and components. Plus the FS-ZE motor that is in it is better than my standard 2.0 in the states with the extra 40hp.(cabpatch)
$1800 should get you a decent car. I have seen them sell for 30,000 yen at auction.
