I've never seen an iX E34, but the iX E30 3 series cars have a unique floor pan, unique engine blocks (at least on the M20 -- oil pump is reversed), unique transmission, as well as pretty much everything else in the front end including steering and shock towers (not just the struthousings), compared to the RWD E30 platform. I would wager that the E34 is the same way given that the driveline technology is shared from the E30. Best idea is probably to import one. Else stick with those slow audi wagons that cost the same dinero.
