I'd really like to see individuals that also can't finance restorations due to health issues and pure bad luck, the kind of people left living with priorities based around every day survival.
While I'm sure Helen could be considered worthy candidate due to her accident I doubt very much that she would have been unable finance the cost of the capris restoration leaving that slot for people in more dire circumstances, I'm now in no doubt that she is of a level of wealth that significantly surpasses the average individual today and maybe the series producers could have considered this when making their decision?
For further information please refer to bangers and cash series 5 episode 4 where she seems very agile getting into a toy car she paid £9100 for her grandson in front of a back drop of cars etc worth 10's if not 100's of thousands of pounds of her own collection of cars and bikes (you'll see the actual blue capri too next to them all!).
I just feel that there are more people on greater need as her pocket seems to be further garnished financially as a result of car SOS.
