Haha, a funny incident happened day before yesterday, i was on the Shell Service station, by my side, there was a New Merc E230 quite dirty, many people were gathered there, the owner of the car and a service man were sitting, that person was having a device like a tablet pc, he was checking the car again and again, i couldnt understand what was wrong with the car, well, i asked the guy who was washing my car that whats wrong, he told that this Merc is standing here since 4 days, the owner was here to get his car washed, incidently the smart key felt on the floor from his hand and the car Engine got locked, they tried every bit but nothing went good, now 4 days later, they hired a Mercedes Service Man from Lahore who was trying to get the engine unlocked ... lol
