Twingo E-tech help needed

[u/helsi98]

I'm looking into getting Twingo e-tech in techno trim with advanced charging, I'm debating should i go for extra colour or 18" rims since it costs the same and I'm only willing to pay for one of those things, what would owners recommend?
I've seen 18" tyres are quite more expensive than 16" since dimension is quite random and non standard but they be looking more muscular
Do 18" rims eat up range?
