I've had both saloons & tourers, all diesel, one automatic.
IMHO there's a couple of things to consider:
Saloons are quieter. Somehow a bit more refined.
Tourers are more practical - it's now our only choice because of Quizzie our Labrador.
And she has plenty of space in the back of a tourer.
If you don't need the practicality of a tourer then I'd go for a saloon but if you do......
Anyone near to you who could give you a chance to look over one? You're in the North East so maybe you'll get lucky
Good luck with your search.
