challenger bhai..yaar im not sure abt the prices of individual items but if u get genuine parts from toyota then definitely rs 100,000 plus........getting it done from a local dealer or shop((no idea))abt that.......and yes the 4 spoke stearing wheel saloon type that u were talkin abt ....it comes with ((SRS AIRBAG))....so bhai jaan i think that stearing itself will cost u around RS 50,000..with the unit and the sensors installed in front of the car......u would like the airbag to work as well i guess......((only toyota motors can install that unit.............the best thing is to go to toyota capital or rawal and ask them abt the changes that u want...u'll get a rough idea....and then try a local shop
