You're gonna go back an get it I bet. You will think on it till it drives ya mad and not be satisfied till you make it happen. Its a wonderful bike that's a hoot to ride. Good luck, I'm thinking you're gonna luv it...
Wait you didn't say 50 bucks did you? Go back and buy it now! Checked out the Breakout today, very cool. Would be my dream bike with a few mods. I may get one when I finally tire of my '02 Deuce
Don't go back this early. Obviously you have the willpower to say No! They have your contact info. Give them a few weeks and they will call you and meet you at the price you want to be at.
Even if they don't, which I'm sure they will, you can comparison shop. Get another dealer to beat their price.
I also agree with Cdonis. Don't ever trade in. They don't really give you money for your trade. You are money ahead to keep it.
If you have a payment on it and can't afford both, sell it to an individual. At least that way it's real money your getting and not an overpriced new bike.
