The rough idle is ordinarily a common and easily fixed problem. Looks clean! http://lasvegas.craigslist.org/cto/1521217997.html
Could be that too, for sure. I still like these K wagons a lot but prefer the Chrysler woodies. I don't know what engine is in this Aries....don't know if it's a turbo or not. No interior pix but it looks clean from the outside. Price is good.
There is a guy on my Turbo-Mopar forum that has an 86 Reliant thats a factory turbo. Said theree rumored to be around 50 that were built for the government. Otherwise the woody wagon is it. Thats why I'm turbocharging mine. Plus mine doesn't even have a luggage rack its so stripped.
