The Leaf is a very nice urban car.
The Leaf is fairly economical to purchase.
The Leaf is low maintenance and reliable.
The Leaf is a reasonably safe car.
Brussels, Belgium is a moderate climate, so TMS or Thermal Management Systems are probably less than useful. Electric cars have fewer fires than gasoline cars, but a TMS raises the risk of fire by having water close to the battery cells. Leafs have had zero battery fires to date, compare with Tesla... or for that matter there has been at least one Audi Etron fire.
The Leaf is fine for moderate distance trips. Seats are fairly good. Quick charging isn't as fast as other cars, less than half what the Audi Etron charges at. A TMS would help on longer distance trips.
