Your car should be okay. Every few years, we get bad snow storms where not even the four wheel drive cars can make it out of the garage, but that hardly ever happens. People drive all sorts of cars here, but like the previous answer tells you, FWD can be very tricky in snow. I have a RWD toyota and that still can't make it up the hill directly behind my house sometimes, which isn't very steep. I have an alternate route though, so it's okay. Once you get here and experience the snow/ice, you may feel like you want a jeep grand cherokee or something a little bigger to battle the winter.
Usually though, Denver especially is always sunny. I swear, WE need to be the sunshine state, and not Florida.
Denver doesn't have a Chinatown, but like any city, there are plenty of Chinese restaurants and areas to check out.
Minimum wage in Colorado is currently $7.02, but it looks like you'll be coming right in time for an increase in that for inflation.
If there's anything else you'd like to know, feel free to email me. I can try and answer any question you have. Overall, I can tell you that Denver is very close to the mountains, so day trips into the mountains are common. It's very outdoorsy and was again named the healthiest and leanest of the 50 states. There's rock climbing, skiing, river-rafting, mountain biking, hiking and PLENTY more to do. You'll find something that interests you. Even if you're not into the whole sports thing, the mountain towns are really great to check out. I love them.
