Trent hit the nail on the head. That's where I would go.
Sometime a wrecker receives delivery of a written off Presara or Prodigy, (Presara and prodigy share the same wheels), with say 2 or 3 wheels damaged and two left. The one in the boot ( always the most desirable) and the remaining one on the vehicle.
Or you may opt to put a new set of mags on it... not my cup of tea, but each their own i guess
