I'm back! After much deliberation we decided to keep Gen's Polo and get a second cheap-but-good car for holidays and long journeys etc. It's a late 2001 530d SE with pretty much immaculate leather interior, and climate all working. All for well under £1000. I bought it from a trusted acquaintance so I know it's a good 'un. It could do with new shocks (pretty much everthing else has been replaced) and the EGR valve needs cleaning but I'm OK with that.
