How to save new / update existing mongoose nested array? Do we need different function to achieve (save new/update existing) this or do we need separate function for each task?

Dummy Model 
var user = new Schema({
    name : String,
    cars: [{brand: String, prices:[ {color : String, value: String}] }],

}

let saveUpdate = await User.findOneAndUpdate(
     { _id: req.id }, 
     { $set: { cars: ----   } }
 );

I have to save new car details and update car model or update price value based on color field
