I have had my car for 17 years (from new). It's very basic but has served me well. It failed its MOT a few months ago so I paid £80 for various minor things to be put right. A few weeks ago, a light started coming on the instrument panel and last time the garage sorted the problem, it cost £200. It's also a bit leaky. I use it to do the food shop and the odd short journey. I've been walking to work (6 mile round trip) although drove when it was pissing down. It now won't start at all, after being juddery for the last week or so. I'm not sure if I want the hassle of a knackered old car at the moment but DH thinks it's worth calling the AA and at least they'd diagnose the problem. WWYD? Scrap it or call the AA?
