Mike, on the Superb the screen wash spray on the optional rear wiper is useless, in fact useless is an understatement and even in heavy rain that wiper judders across the back window making an awful noise. The auto gear change can be a bit grabby at times and late to change up. The biggest issue though is battery drain if the car is sat around without being driven for a while or not driven regularly. I had to fit a solar panel battery charger which charges the car battery via the 12v socket and that fixed that issue.
