All the later models after 97 had Standard Airbags. Not sure what the steering wheel looks like in a 99 tho, could be an airbag in there, but that wheel looks exactly the same as my one (95, no airbag)
Ahh, and its Auto Thats is no TT right there. All the TT had standard Airbags after 96.5(97 whatever)but NA's were optional. I can tell thats an NA, as there is no Trac control button, cruise or electroni spoiler buttons under the stereo.
