i have had the same situation years ago. when my mate crasged into me when i was PARKED! in mcdonnolds car park. and he can up the car park (like a nobend) and as he was having an arguement with his misses in the car did not look where he was going. and yep you guessed it straight into the back on my mini. nocking iit over the curb and 3metres on the grass! nearly in the round about the other side. (tamowrth drive through)
have a look on my website for the pictures. under "my mini" link.
i was also worried about my insurance company writing my car off over a few £100s worth of repairable damage. and yes i did not really want to loose a mates insurance no claims. so he just said he would pay for it. and i still cant believe it today that he payed for it.and a few weeks later in a shitty metro i got hold of.a when round few other mates and escorted him to a cash mashine and yes he payed up alright. i gathered up some more cash just to make sure i had enough and payed the bill. and jonspeed. done it all for £500! so did not cost me nothing.
looking on the bright side he made my mini back end rust free!!!!

a few weeks later that was it. a took it off the road and started the fulll restoration. i had it back last week from respray and now im biulting it again now. all glad it is coming to an end now just so i can drive it again.
oh and when jonspeed did it i just told them to use secondhand parts such as a boot lid, rear lights and new parts being replacment panels. to keep thge cost down and yer they done a great job and all done before stanford hall mini show in 2007.
glad it is all nearly done.
