dk2, they will surely love you here. Since you have already decided to come over, just pack your bags and wing it, in a manner of speaking. Life is an adventure, right? There are lots of things to invest in here, there is real estate, rentals, etc. and then there is soy or wine making. if you have the money, there is no problem. Loads of stuff, just make sure you understand the spanish before signing your life away, this is an advise I would give anyone anywhere (so please do not take offense).
Come and join the fun here. There is never a boring moment in the city and in the country. Tango and good music til early hours of the morning, museums, leisurely spending time at the street cafes...never a dull moment for there is always something going on. New words to learn each time desabasticimiento, reabasticimiento, abasticimiento and retenciones, carpas, fun stuff like that... Your euros will surely go a long way here...everyone will love you here really; re: the ladies - each man's experience is unique so just come on over and join the happy gang....BsAs is waiting for you with open arms. Now is as good as any to come to establish your life here..but again that is just my opinion.
