Iterating over an varchar array?

I am trying to iterate over an varchar array using plpgsql but i get the
this error:

Error: missing .. at the end of SQL expression

My Table:

TABLE1(
Cars VARCHAR[]
)

My Code

Declare
mycars varchar[];
car varchar;
Begin
For car in SELECT cars from table1 LOOP
RAISE Notice "CAR: %", car
END Loop;
END;

Resume, i have a column with a list of varchar type and i would like to
iterate over this array, is this possible?

Thanks,
