I can relate to the incident Tariq is talking about. I own lexus is200 and luckily have had no problems, thus far.
However my uncle had a very unfortunate incident whereby 2 masked men broke into his house, locked his 18 year old son in a room and continued to beat up his wife to ascertain the whereabouts of the keys. They found them and drove off in his 2 day old lexus.
Its a sad state of life where you live in fear because of the car you drive........But don't give in....because of a few foolish dickheads............
