Should I get a fuel efficient V6 sedan?

I'm a 16 year old guy and I want some type of vehicle. The price of gas is going down. I want a Ford SUV or truck but, then I started thinking how much money I'd save by getting a car. Should I get a fuel efficient V6 car? I'm not going with a 4-Cylinder. V6 or V8. I'm not looking for fast but, I don't want a car that struggles to get going. The only thing I worry about is how well it will handle in winter and whether or not I'll get stuck. A car I was thinking of was a Ford Contour/Mercury Mistique. Would that be a good car?

Added (1). I will only EVER own a V6 or V8. Who said anything about RWD? I'm not looking for some tiny car that I don't fit in. Not happening.

Added (2). I'm not looking for some car to modify and waste my money. That's pointless.

I think you completely confused, many 4 cyl cars do better than struggle, that is a simplest and childish concept. If you were NOT looking for fast then your engine size would not matter,

A 4 cyl front wheel drive car would be better in the snow in the winter, if your looking at rear wheel drive 6 cyl then you are CERTAINLY looking for a fast sorts car. Time to really think like a grown up.

Gas price may rise again in the future if car consumer become spoilt with wasteful fuel car
because fossil fuel still non-renewable

ford countour is fwd car, search youtube for 'fwd on snow' fwd
cars still perform bad on snow.
http://autos.aol.com/car-finder/ helps find awd or 4wd (4wd locking capability) cars
then check 'vehicle dependability' rating in http://autos.jdpower.com/new-cars/index.htm
choose car year 2011, 3 years past, that's when car dependability history rating begin to reveal itself

Depending on the car, you can get 4-cylinder cars that have perfectly adequate performance, and most, but not all, V6 cars have great performance. Furthermore, there are very fuel-efficient V8s, where some V6s and 4-cylinders suck gas badly. And some SUVs and trucks get better gas mileage than many cars.

The point is that you can't make a decision simply based on 4-cylinder versus 6-cylinder versus 8-cylinder -- or truck versus car. You have to consider the specific vehicle makes and models, looking at the government EPA gas mileage estimates for each.
