Came in to do an outright cash purchase on a 2018 Tucson on condition that I get 3500 trade in for my 2008 Tucson. Brand loyalty and a "blue sale" is what brought me in. They agreed to the offer.

I made the mistake of believing they would charge the price that is specified online with the accessories I choose less my trade in. I signed and am now waiting on my car which is taking 6 days for delivery despite being told it was in their other lot nearby.

I did the simple math, turns out they actually charged me a little over $500 than what the online price is less the $3500 trade in.

I emailed the sales person and was told that the $500+ is a "dealer prep fee" to clean and detail the car and is charged to all customers. A Google search will show multiple hits stating that this is a well known scam and should be avoided.

I feel ripped off. I don't like my experience and regret going to this dealership all the while I have yet to even get my car. I'm sure the car will be fine once I get it with years of reliable use but I lack confidence or trust in this place and find no joy in picking up a new car from this place and once again to pick up/install the back ordered rims/tires that I also purchased.
