Maintaining Multiple Cars

My father-in-law recently bought another SUV and now he has to maintain two cars plus a couple of motorcycles. It will take a lot of money to maintain plus acquiring a tire chain. It's going to be all good though - they would need more cars to take some of the grand kids to school and to be able to attend to my sister-in-law's needs. Plus they need a delivery car for their office too. They definitely need to have all those cars!
