Things seems to have settled on the search now Dave, the Auto 1.4 is still the cheapest. Results here
The Sharan is a great car, we ran one for three years. It was one of those cars you have in life that feels like noting is going to go wrong, very well made.
I think across all the VAG cars the Sharan is the only one still offering the 1.4 litre petrol, it is a very good engine but the Sharan is a heavy car and it will suffer pulling a full load up a hill, the diesel is a better option if you do anything more than very low mileage.
