Hi, I recently bought a 2019 Honda Fit and let the dealer talk me into an extended warranty for 6 years. He convinced me when he said the electronics could be an expensive fix. My last car was a 2006 Scion XA that had none of these new-fangled things. It basically cost me an extra $60/month for 72 months. Was this a good idea or should I cancel it?

My background is in academic editing and I’m fairly new to the proposal world. What style guides do you follow for proposals? Is GPO the standard, or AP, or Chicago Manual? It seems every sector has their own style—for example, some capitalize Federal and Government, some don’t. Is there a definitive guide or does every branch have their own style guide (and where would I find them)?
