Citroen 2CV, Renault 5 and Fist 500s.
Citroen 2CV: 2 cylinder biscuit tin with no power
Renault 5: 1980s evolved biscuit tin
Fist 500s: as per 2CV but more cramped
Its certainly not 'cheaply built', but it is a light car - those two things being mutually exclusive. It's got the same feel as most of the small sub-compact Japanese cars. If you compared it to a Toyota Yaris, the internal plastics and build are slightly worse in my opinion, and the bodywork also not quite up to Toyota/ Honda standards - but in that same ball park really. Very Japanese in design and construction.
Seats are very good, that I have to say. Power is better than an equivalent gas vehicle. There is no under body rust protection whatsoever as far as I can see, so that for me is the only thing Mitsubishi cheaped out on.
Air conditioning is very good, rear headroom is very good, turning circle is excellent, brakes are excellent.
Boot is tiny.
Access to the front 'engine bay' is all but limited to the hands of a 3 year old.
