Pepping up a 105 Estelle - any ideas?

[Tailhappy]

I am well aquainted with the rear end of trucks. It seems that once behind a truck, the 'pull' it gives offers a real help to me. My 105 can even feel quite frisky when slipstreaming, however when pulling out to overtake, I am faced with a stiff resistance from the air itself and I usually pull back in behind the truck. When taking my family on holiday, I find tucking in behind lorries (safe distance of course) a good way to help my car along on some of the motorways - saves dropping to third gear on some of the heavy inclines. I find travelling east easier than travalling west - the wind usually blows from the west and slows me down further. I travelled south once to Brighton, but no more - the hills are savage down that way I and I am lucky I made it back without damaging my car.
