I can't actually believe that my car went straight through!

The only advisories it got were: the blue led doesn't come on the dash when full beam is on and an intermittent oil light flashing. Both of those are only because the clocks are dead though, i'm well chuffed!
I had just changed the front discs and pads, and as i wasn't insured i took it out for a little run down my cul-de-sac and the brakes were non-existant.

I was hoping they just hadn't bedded in but they were seriously bad. Anywho, the mot guy came and picked up the car and apparently by the time he got to the station they were fine!
Question now is, do i sell it or keep it and get rid of the A-reg one!?
