So there is a collective experience of about 40 trillion years on P-WRX. But everyone has regrets, if your car was returned back to OEM and you were given all your spent $$$$$ back, what would you do different, and why?

This probably sounds pretty lame, so I've donned the flamesuit, but I'm sure everyone has regrets, and maybe some of the newer generations of modifiers can learn a bit from others' mistakes?

For me, I would have spent less on the cosmetic mods to my last car, and invested in a stroker kit and twin scroll.
