Thanks David R - The first thing I did was to add a C-tek quick connector and I have changed the stereo for the new Blaupunkt BREMEN that they have recently re-launched as the lack of coloured twinkling display seems to suit the car a little better. Alastair, I agree that the performance is fine and doesn't need adding to and thanks also for the tip on the sump, there must be a few horror stories out there as you're not the first person to have mentioned this to me. Thanks all for the helpful feedback. Cheers, Paul.
