Modern Autos are streets ahead of what old skool autos were, although there are still loads of bad ones. My Passat DSG is fantastic and this is what I judge all other autos against. The Merc was a harsh and snappy, I guess you'd learn how to drive it though. Vauxhall autos were very decent. As were Nissan's. Hyundai's Tucson's were fekkin terrible, slow changes and unpredictable too. I also had the pleasure of a Jag XE. In normal mode the auto box was lethargic, sedate; very disappointing TBH. In sport though, feck me it was incredible. Knock the engine into sport too and it was simply fantastic, probably the nicest car I have driven.
The worst was the CVTs of the Toyota's and Mitsubishi's - holy feck, they were absolutely dreadful!
