always a good idea to have a full size spare or at least a tyre at home in these circumstances
selling a car for this is a bit of a diva reaction...
(1) True, and (2) I'm sure it was probably the last straw...
Can I just say that I believe the standard jacks are a lot safer if kept well-greased on the threads (I use CV joint grease) and if all pivots are un-seized. In some cars the jack lives in a slightly damp environment under the boot floor (water leaks, wet items placed in boot, etc.) - I know the 500 jack is fairly new but I think it might be a good idea to add some grease, oil the pivots, wind it up and down (unloaded), once a year.
I've used standard jacks for years, particularly with cars too low to get my trolley jack under. Standard jacks were much worse in the Uno, where you only got half a scissor jack and it leaned over too easily. I saw that same leaning problem happen with a newer design when one of the pivots seized, and I also stripped the threads using my 156 jack in a hurry once, which could have been dangerous - hence my comments
