It can be used only in manual transmission cars and is good enough. Look all such devices, padlocks only increase the time of car lifters, but if they come with hydraulic cutter and the lock is cut, it's a matter of few minutes.
When you go for periodic service, check up just put on the cover on the cross. The cross can only be stressed if you mistakenly insert the key in imagination switch, start and rotate the steering when the lock is still there in the cross. Otherwise the lock will not cause any problem.
Yes getting that trunk mat or tray from Hamza Younas autos in Saddar for 1200 rs. The one I saw in F-10 Shahid Autos for 11 was not good looking. It will just protect the carpet from leaks and dirt, but I am not sure objects will stick to it. For instance a water bottle, my camera bag etc.
@fazalwahab11375 that looks great. I will explore the options.
