Whilst I would agree with DaFlake about just getting a set of wheels to keep you mobile, I must admit that when my car had to be recovered last year, my loan car was arranged via Mini Emergency Service through Europcar who had just taken delivery of a number of BMWs so that customers of the BMW group (or equivalent "prestige" type brand) could be provided with a similar type of loan car. From past experience, Mercedes also have this policy.
In fact some of the brands (BMW and Porsche spring to mind) have taken to lending you a superior car to the one you own, presumably in the hope of enticing you to spend more money! When my
MCS was in for a new rear bumper after someone rear-ended me, I got a 3-series M-Sport as my courtesy car

. Either way, good car or piece of crap, I'm not too fussed as I'm usually just glad to be back in my Mini at the end of the day!!
