We like all the boy's toys with the exception of the built in Satnavs which in the majority of cars has huge drawbacks as you cannot add your own POIs i.e. Archies Campsites. Plus when it is time to update they charge you an arm and a leg plus some. TT gives us updates 3- 4 times a year free of charge and we can add our own POIs.
I'm in the "buy used, relatively low mileage" camp too. No point in buying brand new....you drop a fortune as soon as you drive off the forecourt & you don't have the (potential) brand new car problems. I have remote monitoring on my gas boiler so it comes as no surprise car manufacturers are using it too.
