Hi Everyone. I am new to this forum and I am just thinking about ordering a Tiguan 150 TDi DSG R-Line in white with tyre pressure sensors. However I am being told that lead times are currently 17-20 weeks. The problem I have is that I have a car to trade in.(VW Passat Executive Style). I have been quoted a value for trade in currently. This may appear a silly question but, once I place an order with them, do they have to honour the trade in value or do I find out what it will be only when the car is ready? My opinion is that once I have placed the order and they have agreed trade-in price, that is what they must honour as they have entered into a contract.
