I could be wrong...but I believe air suspension didn't come around till 93..... Also the cargo room is the same in LWB and SWB.....Just more leg room... Look for rust on the lift gate in the rear...see if it opens freely, a lot of them stick. go to
www.rangerovers.net for a lot of the problem check list. problems I have had with mine have mainly been caused by off-roading.... all but the alternator... Power steering seems to be a common leak area as well as oil coooler lines
