Colin motability do help if you have a genuine reason to change early. Rules that they waive do state at their discretion and thats what we all agree too.
someone said your car will be more saleable if serviced and motd and ready to sell as a one owner car, as I said they are very unlikely to loose money.
There must be an added cost involved to change early as they are breaking a credit agreement with the manufacturers and they state there is a max number of times they are willing to do this, before they find you unsuitable for the scheme.
