Im out on track fairly often but not in a road car. Driving an auto around a track waiting for it to decide what gear it should be in is no fun and to be honest a total waste of time. Driving a car with DCT around a track is so much better than manual.
As for driving around a track in a coupe vs cabrio and telling the difference is pretty easy. One is windyer than the other.Seriously though cabrio's are sometimes stiffer than coupe's believe it or not but with road tyres you wont tell the difference and all you will notice is wind.
If you like track days, DCT would be far better than auto and manual. If you never do track days then auto 100%. If you claim you want to connect for the sheer driving pleasure and become one with your vehicle on a level no one else understands then go manual but thats subjective and differs from driver to driver. But having said all that it also depends on what vehicle you are driving, for example a M4 then DCT all the way, an E30 M3 then manual as the auto box's were kak in those days.
As for life of the gear box, im not sure manual lasts longer than auto or DCT? I think they are pretty even now with manual possibly being slighty less reliable than auto's due to poor drivers or driving errors.
Its the same as owning a 4x4. How often do people living in the city actually need or use the 4x4 capabilities? Once a month if you lucky, but that once a month or once a year trip is all you need to make it worth while.
Some auto's are programmed wonderfully and the manual override means true manual intervention, those are fine on a track, then you have rubbish that even in manual mode will still up or down change those suck.
(no offense)
