I bought my 500E because I needed a family car but I was not going to sacrifice power and performance. I need to get a car seat in the back but I cannot find a place to put the bolt that the strap attaches to. In Canada, it is law to have the bolt for the strap. Anyone have any input about my predicament? I personally feel the seatbelt and seatbelt lock is enough but I never want to compromise my son's safety. TIA.
