Ok guys my friend just bought a new car. A nice Cadillac Ctz really nice leather seats and everything. Well he bought it, and when he went to fill out the paper work he had forgot something. He forgot to print off his online insurance quote and bring it in to save an extra $250. Because a lot of dealerships will give you a discount if you have your insurance rates all ready for them to analyze.
This was another common mistake, but it could of been worse than $250 he could of got into a wreck on the way home and been in a long legal battle but he wasn't. :)
