Is car home's short message about the reserve price reliable?

Reliable. Car home has requirements for merchants, and the inquiry message must be lower than the lowest quotation. It is best to consult the local 4S shop.

There is a big difference between the national price and the local price.

However, what I can confirm is that you have taken a fancy to a car and want to consult the lowest price. You must go to the 4S store to see the car and ask, otherwise no store will tell you this easily. You can directly pay attention to the quotation and contact information of dealers on the car homepage. They have both a running-in shop and a 4S shop. If you want to get a relatively credible price, I think you'd better go to the store in person and talk to them face to face.
