Yes maybe, I know mine was well fettled by OCD owner before I had it. Upgraded starter relay, brown connector sorted, better battery etc. etc.
I am wary of leaving it too long though before using it, mainly as my battery doesn't seem to reach the voltage it should.
For MOT I had to sort both brakes as well not turning brake light on. Front was just the microswitch, rear the garage had to fabricate something for rear brake to work. Oh, and if I rarely use front brake I never use the rear as its non-existent.
