you have to take it with a pinch of salt, like the time brand new discs and pads appeared on the car but never got mentioned, or the fat that most have brand new tyres at the end but again, aren't mentioned.
We all know that in reality making a profit out of buying an old classic and fixin it up is difficult and if you threw in the man hours they would never make a bean let alone the £100 they seem to acheive on most cars lol!!
