Notation related question

I want to make a function that takes an argument V and returns a list 
build of V with subscripts 1,2.3: V -> {V_1, V_2, V_3}.

I symbolize V and define the function:

Vec[V_]:={V_1, V_2, V_3}.

It works as I expect for V but Vec[X] returns {V_1,V_2,V_3} instead of 
{X_1,X_2,X_3} as I expect.

Anoter related (I think) question I have is how to define a _Vec type so 
that once I declare X_Vec the internal representation of X to be {X_1, 
X_2, X_3}?

Thanks in advance,
