I've got a N reg Vectra 1.7TD that I no longer need. The brakes are on the way out (have to push foot all the way down and still they aren't great) and there's a minor grinding noise on the rear drivers side. It's due MOT in September so not sure what to do. Should I sell it and make the potential buyer aware of the problems or just scrap it? If I sell it what is it worth?
