In the presence of water (e.g. aq. HCl) there will not be any 'anhydrous' AlCl3 present. In fact, in aqueous HCl, there really isn't much 'HCl'; it dissociates to H3O+ and Cl-. What you probably have is a solution of hydrated Al+3 ions, chloride ions, AlCl4- complex ions and aluminum chloride hexahydrate, with perhaps other mixed and hard to characterize species present.
The life time of 'AlCl3' will be very small. So I guess you can say it is produced, but good luck isolating it.
