Car SOS - how good are their restorations?

[Esceptico]

I enjoy watching Car SOS but wonder about the quality of their restorations. From what I know of other people doing this privately, a full restoration (which most of them seem to require) seems to takes months or even years yet Car SOS seem to turn it around in a few weeks (admittedly there seem to be lots of people working full time on the car during that period). Are the end results actually good restorations or just look good for the show?
