Ok, well my younger bro needs a car. SoOo, I'm gonna let him have mine, so I can get a new one!

Ok, well not new, but a new used one. Anywayz, I'm looking for 6G Accord Coupe EX 5speed b/c I can get my mods from the car I have now over to my new puppy so I don't really have to start allll over. I know it's hard to find a blue or red one, but i'll get my hands on one. Anywayz, a couple of questions about insurance.
1. How much more can I expect to pay per month by switching from a 4door to a coupe?
2. Is true that if you get a red car, you will be paying more per month? If so, how much more?
Hopefully, I'll have this new car by the end of the summer. Thanks in advance.
