After market e.c.s?

[Davey]

Hey all my names Davey. First time blogger, long time observer. My conundrum is that I'm looking to get a 2008 fg xr8 ute, have found a good one. But unfortunately it is pre factory ecs (electronic stability controll). Does Any one know if u can get aftermarket fitted, and or is it worth it? Or perhaps I should hunt for one with esc standard?
Yr input would be greatly appreciated. Regards davey.
