My DFather got an automatic a few years ago, having spent a lot of time in the USA in recent years with hired cars. He loves it.
DH also used a hire car in South Africa a lot over the past 4 years, as well as on our trips to the USA and Canada (I have driven there too but he tends to do most as he's more comfortable with it).
Having loved it so much abroad, for his last car DH bought an automatic too.
At the time, I had my own car (manual) but we'd take the estate on big trips to see family. So I am quite comfortable driving the automatic too (we all get sent off to do things in DDad's car at times, so we've all been taught how to drive an automatic - "take your left leg and throw it over your shoulder - now just use your right leg while driving"!!).
Unfortunately, as DH was overseas so much, we dropped to a single car last year and changed both for 1 new one. I lost my little Golf, but as we couldn't get what he wanted in an automatic, we ended up with a manual estate.
I wouldn't be surprised if:
a) we get an automatic again next car if DH can find what he wants with that gearbox; and
b) our next family car is not an estate but a jeep-type car (up high off the road); and/or
c) I buy myself a runabout again now that he's not travelling so much again (or else a moped - which DH is terrified I WILL do!!)
