Which BMW is good to drive in Winter time?

I'm about to get my license in a few days, and I will be buying a BMW from my cousin, and he is a mechanic so I trust him. He has a number of BMWs which he drives himself, and as a mechanic, he sees BMWs as a reliable car. He owns many BMWs, he buys from auctions, primarily specializes in BMW as a mechanic but fixes other cars too as a part of his job.

I know I'm going to have a lot of answers saying BMW is a bad choice for a first car for teen, but in the province I live in, BMWs are cheaper on insurance than Toyotas and Hondas as a result of a safer, stronger body, as well as low theft rates BMWs have, according to an insurance company I spoke to. My cousin even recommends BMW as a first car, and he is a mechanic. My dad says I should learn from his experience and get a Toyota, but Toyota is more on insurance, and I at more of a risk of any imjuries in such a car since it dos not have a safe body, which is one of the main reasons I'm not getting one. I work a part time job earning minimum wage.

When the cold harsh winter season comes, I want a car that is safe, consumes less fuel, good on gas, and such. Any recommendations?

Added (1). And say "ask your cousin, he should tell you blah blah blah", I just wany recommendations. The model and year as well. Any other specific info are welcome.

The biggest thing with winter driving is being safe. With reduced grip, performance drops down quite a lot.
many people will argue that front wheel drive is easier to drive in winter. This is because with front wheel drive, you have the weight of the engine over the driven wheels to give you better traction on acceleration. Unfortunately, this added stress on the wheels makes it easier for understeer to happen.

understeer is when your front wheels are turned but the car does not follow the path the wheels would normally take. Instead, they push forwards.
a BMW is typically rear wheel drive. A rear wheel drive vehicle will typically be less prone to understeer and more prone to oversteer.
oversteer is when the rear wheels slide out and around the car in the direction of the turn.
understeer is easiest to correct because it just requires the driver to let off the gas and keep turning where oversteer is much more difficult as it requires countersteering and throttle control.

a keep driver will typically be better with rear wheel drive but an inexperienced one will not.

I like rear wheel drive because if the car is ever going to slide, with rwd, I still retain control of steering and braking where with fwd, steering and braking are impossible once the driven wheels start to slide.

if you have gone through a winter driving program, a BMW is a great car to start on. If not, then it might be a bit tricky. The biggest thing which applies to all car types is to accept that you can't drive the same in winter as you can summer. In winter you must drive slower and leave a lot more room around you.
while things like front wheel drive or all wheel drive may help with accelerating, they don't really help with stopping. Only good winter tires and a different driving style will help with those.
