I asked this question to a few male friends of mine. He said his BMW costs as much as his wife anyway. Think of the maintenance and upkeep costs, the cost of the parts, servicing and not to mention the money to maintain the shine in the car with regular car grooming.
Cars are like big toys to big boys.
When they were young, boys were encouraged to play with toy cars. When they grow up, cars become an obsession with some men. But as one friend said, better for him to spend his time with his car than off gallivanting with other women. I thought that was a pretty funny acronym. Guys have all sorts of funny nicknames for their cars.
