Vehicle Purchase—best place to buy?

Thx for the contact and thoughts,
we are relocating there this fall and have driven rental cars there without issues on our previous half dozen trips with no issues, but think it may not make sense to have the hassles of owning a car. Looking at the nissan dealer, but also just using local taxis and walking as we won't be in a hurry..
any other thoughts from locals on owning a car vs not for living near la ropa (cero de vigia)?
thx!
Wade
