Me and my dad put this on my Megane Coupe on Thursday. It's Called a Mul-T-Lock incase anyone doesnt know. It does the job. Bit awkward to put on since the leather gator keeps getting trapped. I still need to tidy up the install a bit. We had to cut the plastic back on the centre console to get the bracket into place. With lots of hammering and banging to get the bracket twisted to the shape we wanted it all went to plan. The bracket is bolted to the floor with special tamper proof coach bolt things.
About £150 to buy i think. We had this one lying around in the garage so thought its best if its actually on a car.
