rofl!
i'm sure your mother would then point out all the outlay she spent on your childhood etc etc.
but back on topic i had read that the ACC normal mode is actually an adjustable one, i.e. even without pressing a button, it will firm up the suspension if it thinks you're pressing on a bit. however you don't get the sharper steering of the sport mode.
comfort mode would be good when on motorways and around london there are soooo many speed bumps.
i do do the odd track day so i suspect ACC is a good option to have and by and large it has either had neutral or positive reviews, well at least no-one hates it! if i can get a good deal then i'll get it i think.
