I was given a loan car until I can sort something out. But this one is an Automatic, and I really really really hate it.
I think I've found the problem...!

Multi-user, poorly maintained, generally used and abused...
My Mrs's auto does exactly what you were compaining about, but only because she STILL hasn't serviced the thing and it needs the transmission fluid changing!
Never driven a auto what are like off the mark ? i would hate a sluggish start are they comparible to the manual of the same make 0-60 ect..
I've driven three autos:
Vauxhall Corsa 1.4LS - Nice, nippy little thing, definite girl-racer car. Can feel the gear changes, but still smooth.
Mercedes 250 Elegance - The Mrs's car above. Big boat, nice and relaxing but still fun to drive, horrible if not maintained.
BMW SomethingOrOther - 520, I think it was. Has similar acceleration to my bike (1.2L Sports Tourer, does 0-60 in 2.8 secs)!!!
Seriously high power compared to the other two. Unfortunately, everything was all electronic, so it also felt quite detatched from the road.
