Hi, I am looking to sell my 1969 Sprite Alpine Caravan and I'm wanting some advice on how much it is worth. It is 4 berth (double bed + bunk bed) and is in good condition. Has original documents with it such as caravan maintenance manual and receipt of purchase. Has working double gas hob and grill (not gas safety tested) and foot pump sink. Can be hooked up to electricity supply. Also includes caravan cover and awning. Any help is much appreciated.
