I once owned a 1989 280GEL and loved it, 15mpg everywhere, motorways, side roads, in town, no difference. The diesels fare a little better, but still in the lowish 20's I think. I have not looked at the newer ones as many of them are left hookers. Bought my G in 1999 ish for about £15k, good versions are stll fetching around the £7-8k mark. I would like a 300GDL auto, but almost as rare as rocking horse droppings.
