I live in the 'zone 2' suburbs, as such. I work from home. I have the windows open all day... I tend to notice stuff going on around.
Recently I've been noticing a metallic graphite Lotus sports car going around several times a day. I.e. loud little engine, revving into the same corner it does each time, and away. An hour or two later, it's back, and does precisely the same, it's revving engine distracting me from my work...
I'm unaware of any nearby Lotus dealership... so what might it be...
