After 1 year of Smart-Auszeit again a Smart?

Hello, I had a Smart BJ 2007 with 71 hp until about a year ago and sold it after about 50,000 km and 5 years of stopping time. I always drove the Smart as a second car for the trips in the city, to work or the simple short distance. Meanwhile I miss the small, reliable Smart which has always brought me well from A to B. So I am faced with the question “should I buy a Smart again?”. However, it should become another engine, because I was not satisfied with the 71 hp. Neither a low consumption, nor really fixed. Therefore it would be possible: – ca. 2011 – Electric Smart – 84 hp or Brabus – or yet a Diesel (low consumption) – Farten to work about 7 km a distance – Short distance sometimes only 1 km – shopping etc. Hope you can help me a bit.
