I still think you should avoid a turbo car if maintenance costs worry you, not just because of the turbo but usually all the additional stuff the turbo versions require, more expensive filters, oil, larger tires, brakes and pads and even plugs. Outright performance might sound fun on paper, but once the costs come in youll be asking yourself was it worth it. Also with a less powerful car youll always be wondering how it would have been with more power . Though IMO if the car is fun to drive power really shouldnt be the issue cause there will always be a faster car than what you have.
