Hello everyone.Today afternoon,during a boring tourism lecture in the college,I was thinking about installing seat covers for my i10.My query is that I have seen some car car accessory shops detaching seats from the car to install a seat covers.So in what situations seats have to be removed from the car??I don't want such thing in ,my new new red beauty!!Also one of the shops was having a sewing machine for seat covers??Why would the shop need that machine??Can it be customer's customized seat covers??
