Oh god, a Smart.
Let me tell you something about these smarts. They aren't worth a crap. First of all, they actually perform better on the motorway than in the city and they are a death trap. They are built with a very high strength "life cell" design but what it does in a crash is not absorb the energy, instead you bounce around and your internal organs and especially your brain collide inside the body. These secondary collisions are what actually kill you.
There's also an issue with side impacts and people getting ejected from these cars.
I remember it being tested on 5th gear, found it...here's an eye opener. Do you REALLY want to drive in this?

Also, the crank case evac was not up to par, leading to all kinds of carbon deposits issues with the turbo. You can't buy replacement parts for those cars, they are literally throwaway cars. For instance, need a new light bulb for your tacho? You have to buy a whole new tacho unit. Here in NL there's a specialized breakers and parts company who do rebuild, refurbish smart components and sell small items but otherwise you're screwed. I remember the little engine is only expected to last 120.000 km. What kind of life expectancy is that. Many of these engines have lasted for as little as 60.000 km because of the evac issues.
