This E30 is as sketchy as can be in terms of legality, let alone the reputation of the builder. It's using a VIN off of a US spec car to be legal here which is VERY illegal. That is no where disclosed in the ad or anything. The feds can and will confiscate a car over that and crush it. Plus jail time, so buyer beware.
