I've not cleaned the EGR valve yet, but have seen the video guide and plan to do it next weekend. I appreciate the tip though. The car will be getting mixed use, but there will be plenty of longer journeys including a fortnightly trip from Windsor to Plymouth for the next 10 weeks (440 mile round trip) for my wife's work.
The previous owner had a daily motorway journey and the average consumption is currently at 45 mpg. It was at 47 mpg when we got it, but I made sure I blew any cobwebs out during our first tankful, which is averaging 25 mpg.
The interior was in great condition already, but I gave the plastics a good clean and I'm going to give the upholstery a deep clean next weekend too. Then I have some stonechips to sort out on the bonnet mostly followed by a good machine polish. I'm temping at a bodyshop as it happens and will get it done if we have a quiet moment or I might just buy a DA polisher and do it myself.
The other thing I'd like to do is get rid of the awful front number plate holder. I think they really let the styling down. I haven't managed to find a guide to removing it, but I've not searched very hard yet.
All that said, the car is great as it sits and drives beautifully. My wife is very happy with it.
