I know what the sales numbers are, and I wouldn't call it a sharp drop in sales. Similar drops in sales happened between 89 & 90, 91 & 92, 93 & 94, 97 & 98. Yeah, I know the sales numbers. I mean, maybe consumer feedback back then was painting an unpleasant picture, but looking back on sales numbers alone does not imply to me that the XJ was ever struggling.
Back on topic: I'd stick to a 3.4 myself due to the ease of swapping then I'd shift my focus toward restoring and/or improving other areas. I mean, I'd drive the 2.8 for as long as it lives. It may be weak compared to a 4.0, but it still does the job.
