Comprei há 2 meses o Seat Arona novo DE 95 cv... ´Trata-se da versão base...
Estou muito contente com o mesmo...
Tem um ótima posição elevada da condução, é económico, tem uma bagageira com uma boa capacidade de arrumação...
Considero que este B Suv tem uma aparência bem desportiva e atraente...
Só tenho pena deste carro não ter instalados de fábrica os faróis dianteiros de nevoeiro, nem a câmara de ré acho que isto faz muita falta a nível da segurança da condução... Só a versão superior do carro é que traz instalada isto tudo...
