The M800 is $3750 fitted and tuned, NIL options enabled.

Its an extra $450 for ALS and L/C and $540 for AVCS.

actually depend where you tuned your car, coz like for example speedworks would charge $800-$1200 for initial tuning.

I paid $500 for the advanced option enabled 2 years ago, plus switches and wiring

what is -- avcs??

it's vtec in subaru, only available for all my01+sti and my03+wrx
extra $540 as Psyched mentioned for motec software

cool thanks
