Thanks again, all useful advice.
Think you are right Watts, if I sit on the fence too long all I will end up with is splinters & no car!
I have been spoilt with optional extras over the years, think I've had most of them going on different cars, latest was Self Parking which I have had for a year & used it..............never!
I will have to decide on what I "really" want & probably compromise on the rest.
