Test drive one before you buy. 6 years ago i was looking to upgrade from my manual 350 to a 370. I was kindly given a brand new auto 370 from the local dealer to test out while my zed was in for some work. I covered 2000 miles in those two weeks heading to north wales for a wedding and doing the zed welsh weekend.
I have to say, i really did not like the auto box. Gear changes felt sluggish, they felt wrong at roundabouts and there was a big delay. I really did not like it. I bought a manual with the synchro rev matching and couldnt be happier, love it.
However, a couple of years later i drove Adrians 370 which had been significantly modified. The gear changes were much more responsive and as the gear ratios were shorter (with the extra gear) the car felt much faster than my manual. it was a much nicer experience to a standard auto.
I'd still pick the manual though but Adrians car was a beast that put a big smile on my face.
Ultimately its horses for courses, some will love the auto, others not so do test one out
