When we bought our 2nd hand car (6 months old) a couple of weeks ago, we took the smallest amount of finance possible to get an included Service plan. We didn't really want finance, but given it gave us the equivalent of two services, it seemed worth it. We were told that providing we made three payments before settling, we would be able to retain the service plan, thus effectively getting the plan for the cost of three months interest.
Has anyone else had experience of this? It seems strange to have to make "three" payments before you can settle and retain the service plan. The Finance T&C's don't seem to make any reference to it, nor does the service plan.
I had considered making an initial overpayment to further reduce the interest, but leaving just enough finance for the three payment requirement.
Three payments is the point at which the salesman gets his commission on selling the finance and unrelated to the offer..
From what I've read they cannot take the service plan (or other incentives) away from you if you withdraw. Read the thread I linked to earlier for more information (or google around for other threads on the matter). Note I've not personally done the service plan thing but am.confident from the experiences of others online.
