i seriously doubt it'll be worth the time, effort, and money to add VSC... if it even is possible. there's far too many components, and i'm sure its a complicated system. Didn't your friend check all the options on the vehicle BEFORE he bought it? 
According to toyota.com the VSC/TRAC is not standard and a single option on the SE (not bundled with leather sport seats etc or anything). It's sometimes funny how they do that. My XLE had an option package including Nav and VSC/TRAC. But I agree, I would have thought VSC/TRAC is standard on a SE...but I guess it's looked at as a safety feature and not a sport edition feature. Upgrading afterwards is probably not very realistic.He assumed it did because of the package he got, when i turn my key just before im about to start it ( all the lights pop on, including VSC and Traction) well hes doesnt. Kinda feel bad for him, prolly excited about the car and didnt think twice about it.
well you know what they say when you assume...He assumed it did because of the package he got, when i turn my key just before im about to start it ( all the lights pop on, including VSC and Traction) well hes doesnt.
