Buy Smart, Yes or No? PLEASE FOR YOUR MONEY

Hello guys.. I’ve been thinking for a few days if I should buy a used Smart CDI ( from mid 07 ) or not. I find the little one pretty chic. Another purchase motive would be the low diesel consumption and the maintenance. Unfortunately I read a lot of bad things about the Smart and therefore I would like to hear your opinion.. I am a student and in any case depend on my car for the next 3-4 years. Therefore I can’t buy a car with which I am looking for a car. Before I change my 2006 Peugeot 207, which is in TOP condition, I need to be sure that I don’t make a mistake. My Peugeot is really running 1A…and he wouldn’t make any noises before 150,000 to 100%… That the smart doesn’t offer as much comfort as my current car is clear to me. I’m primarily concerned with the fact that I’m cheaper than I am. What do you think? What are your experiences with the Smart? Are you satisfied? Do you recommend the change to me? Are there any models that may be more vulnerable than others (from the engine or year of construction), if with which one am I on the right page? Thanks for the answers…
