Dunno why the downvoted. Smart cars are objectively bad cars. For a similar price you can get much better cars like the Honda Fit.
However, they did have their charm when you were getting charged per minute driving them. Handled like a go cart. Gas is either 100% or 0% and you just modulate the brakes.
Depends where you live I suppose. A Jazz (what it's called in the UK) starts at £15k, a Smart back before they went electric only in this market was well under £9k.
