However, some reviews highlight concerns. There are reports that the dealership may reset check engine codes to hide issues, and they sometimes buy junk cars from auctions and sell them at higher prices. Some customers feel they were misled about the condition of certain vehicles, and delays in getting titles have also been noted. Despite these negatives, some buyers have found great cars and had positive experiences, especially when taking time to carefully choose their vehicle. Customers from out of town have appreciated the professionalism and willingness of staff to help, even after hours. Overall, H.I.S. Auto Sales is seen as a typical OKC used car dealer with both good deals and some caution advised. Those seeking a straightforward, no-pressure purchase may find it a good option, but it’s wise to be aware of potential pitfalls.
