// Ford instance being copied by ferrari i.e ferrari and ford have two different copies 
// We declared `ferrari` instance using `var` (mutable now). In Struct, it always behaves like immutability so we have to declare his instance (i.e ferrari) and variable (i.e name) using `var` only to get mutable behavior
