Early ones were VW beetle based Second gen..were Corrina based Third gen..were sierra based There are a few range rover and diahatsu based ones about but rarely seen or heard of now. Some (very few) come with (normal number plates) but most on a Q plate. 1600cc upwards is best for normal use. Mine has a 2000cc pinto with a five speed box.
The hard core are here we just don't say much unless asked. Most of us have been there and done it and warn the T shirt out,lol But we're still here so feel free to ask away you should get all the answers you require (some of them might even be the right ones)
