I have a dealers license. The fees for Manheim auctions can vary by location, auction type(repo, consignment, specialty) and sale price. The fees are generally pretty reasonable. If you are purchasing at an auction in Ohio, the tax you pay on the vehicle will not be any different than buying at a dealer. It just depends what the sales tax rate is in your location. If the auction is in another state it could vary depending whether they have a sales tax reciprocity agreement with Ohio or not.
