Lego technic 8284 dune buggy retail

Product Name: Lego technic 8284 dune buggy retail
technic 8284 dune buggy set. Open box. Contents appear to still be in the original factory sealed bags. However I was perusing through the manual and I noticed that there was a motor that I did not see in the box. I don't know if this set includes a motor or if that is sold separately, however I did not see one in the box. Other than the motor retail it looks like everything is in there, however I am not 100% sure. See pictures for details. Only includes the pieces shown in the pictures. Ships in the original box, which has some reps and shelfware from age.
