I honestly dont know how i'd react in that sort of situation tbh, fingers crossed its one myself or the wife never find ourselves in...
Sensible side of me thinks that if they went to the trouble of breaking into our home and coming upstairs for the keys then i wouldnt want to put mrs beddie in any danger for what is an easily replaceable lump of metal, the other side of me couldnt bear to let my hard earned drive off without any protest...
My cousin was unfortunately faced with this a few months back, 2 lads came into his house early evening and demanded the keys to his S3, he put up a fight but got an iron bar across the head for his trouble and a trip to hospital, scumbags didnt expect any resistance and legged it without the car, quite possibly the same scrotes came back 3 up a couple of weeks ago and took it this time...
His dad this time managed to chase them to the car and smashed the windscreen and back windows as they drove off to help make the car more noticeable, it was found in one of manchester's less desireable areas a few days later just parked up
Bearing in mind his dad is HUGE and had a bat and was running after them in his boxers, not sure i'd fancy a 3rd time lucky attempt
