Welcome mandymoo. I am trying to remember how much an alternator was the last time I bought one, I think it was around the £100 mark, a 2nd had one would of course be at least half that, but you don't know how long it will last. Also, most motor factors will charge a returnable surcharge (deposit) if you don't take the old one in when you buy the new one, as they are usually exchange. Can I ask who has told you you need a new alt? Did you get the battery checked too? Just wanted to make sure they are not trying to sell you something you don't need..........
