My IS250 absolutely stinks when I've been booting it, even for a short while. It's very hard to describe the smell - not catalytic converter I don't think, just well... hot. If anything I'd say it smells like brakes (although I'm not too heavy on them), tyres (even when I'm going in a straight line), or clutch (even though I don't have one). It's still under warrantee so I'm not concerned, but is this normal or something I should point out to the dealer? Thanks for any help.
