This is a subject that has always been up afor a LOT iof discussion. You can find 01Esw over here, but Bentley Publishers list 01E as a Quattro. I have an 01X, which is the two wheel version. They come up on eBay over here all the time. I got mine for £200 and according to my mate who is stripping it, it looks like it only has a few thousand on it.
