Driven a fair few Aygo's, and quite liked them. Obviously, they were all hire cars, so are the world's fastest car. Nothing, aside from the slightly cramped interior, to dislike about them. That said, nothing to really love about them*. Its a tool to get you and 1 passenger somewhere.
No idea on reliability, but lacking french electrics should be a positive.
*Ignoring the hire car factor, and the fact I always have run in under powered cars on bicycle tyres
