I would keep it, I don't know how often you drive your car, but in the spring, summer, and fall, I drive it all the time (rain or sunshine). With a bike, it's probably not that much fun to ride in the rain, or safe. I would think you would get more enjoyment out of the car, not having to worry about the weather, and can relax somewhat. I never rode a bike, or do I plan to, because I would probably do something stupid and end up being road pizza, lol. I don't follow the bike market so I have no idea money wise if it is a good trade or not, or how fast it is.
