Keep the SC and buy something to commute in. The problem with using the SC every day for such a short journey is with engine temperature. If you don't create enough temperature in the engine to burn of the condensation then the engine will start to detiorate faster than with good use. You need a twenty mile run to get the engine up to correct operating temperatures. Of course this assumes that you are not driving flat out for twelve miles! The same applies to other engines but I don't care about other engines.
