Is it bad or OK to call a proxy from a VO?

If it's not OK, why not?

Let's say I have two different proxies, one for cars and another for car parts used on different cars. If I open a car part I will have the ID to the car it fits on, so why can't I retrieve the car proxy in the VO and return the related car VO right there?

package com.carparts.model.vo {
	public class CarVO {
		public var IDCar:int;
		public var Brand:String;
		public var Wheels:int;
		public var Color:String;
	}
}

package com.carparts.model.vo {
	import com.carparts.ApplicationFacade;
	import com.carparts.model.CarsProxy;

	public class PartVO {
		public var IDPart:int;
		public var IDCar:int;
		public var Price:Number;
		public var Size:Number;
	}

	public function get car():CarVO {
		// The CarsProxy has a dictionary of all different cars indexed by IDCar.
		
		var carsProxy:CarsProxy = ApplicationFacade.getInstance().retrieveProxy(CarsProxy.NAME) as CarsProxy;
		return carsProxy.carsDictionary[IDCar];
	}
}
