I get a funny smell when I get back from driving, its when-ever I have been up to speed, not nesecerally ragging it. I couldnt find what it was, its just around the engine bay area. It could be the brakes or just the fact my engine is old and there will be all sorts of crap around the engine bay that start to burn away (oil/grime/elephant poo) when the engine gets hot. Not worried myself, its still going, its serviced regulary and if it starts to be dodgy its sorted straight away.
