As above, try out both manual and DSG cars to get a feel. I never had the opportunity but imagine I'd have gone for DSG in retrospect.
.... x2 - Definitely try before you buy.
I reckon you'd have gone for DSG too, Jas [or is it Jaz?]. Just the fact that your open-minded about DSG suggests you'd get on with it. Most of those who don't like it start off thinking of it from what they know of old-fashioned automatic and also that not fart-arsing around with a foot operated clutch and your wrist is somehow not manly. The result is that they don't give DSG a good chance - It offers many options and you need at least 1,000 miles to become naturally fluid.
Mentioning no names, and I used to be one of them, but I don't understand DSG drivers who only ever use 'auto' D-mode (though I did often use S-mode as well).
I like DSG/S-tronic so much that I simply wouldn't ever consider owning another car that didn't have it or its equivalent. Thank goodness Ferrari's now have such a system!
