Used Nissan Sentra for Sale near Kelowna, BC

I love saving money on gas. There's no question about excellent mileage with this car. It's also quite hardy, surviving harsh winters quite well. It also has an amazing amount of storage space in the hatch. On the down-side, I feel very vulnerable in a potential accident because everything is so thin. I question how well it would hold up in a crash. The engine is not very powerful and I lose speed going up-hill. Passing on the highway is only possible on flat ground, or , preferably going down a hill.
