(I also don't think you can refer to your car as being "The" BTTF car any more. There is more than one in the UK. - Just a mention)

The rear drive shaft gaiters are not an MOT fail, but should be replaced asap to prevent dirt ingress into the CV joint. Ideally if the tear is bad, then the joint should be disassembled, the old grease cleaned out and replaced with new as grit in the joint can damage the bearings.

I'd imagine an hour of labour would cover that work (removing driveshaft, dismantling joint(s?), cleaning, greasing and re-installing)
