to be fully truthful with u mate, the 430 is the one to have, as said it is a stunning engine, and economy wise,. we have just got back from, Newcastle done 403 miles so far and the trip comp is still reading 100 left. that's around 500 to a tank of fuel, and some of that was on the small roads, and undisclosed speeds were hit several times on the journey, we have a 95 400 aswell, and although the resemblance is there, the 430 is far the superior. hope this helps
