I'd have no problem with an original A. Suspension is crap - manages to be harsh and not sporty, think Audi but taken to more extremes. ESP, ABS, BAS on all models, front drive and airbags too.
Steering column joints get screwed, probably due to afterthought of a right hand drive setup, and aren't cheap at main dealers. Suspension knocks and rattles its way to an MOT fail but other than that they're safe, practical and reliable, driving position is odd but good from a visibility and control point of view. I ran one for a year and did over 30k miles in it, if I needed to save cash and buy a small car I'd have another (though as others have mentioned a new shape one or a B is a much better car).
Plenty of them around, A160CDI is very economical - diesels suffer usual injector issues. Plastic panels and bumpers will take minor knocks without denting too.
