First off, I don't think you can compare the previous model Genesis with the new model for resale value as they are very different. Read the reviews.
My 5.0 had a sticker of $56k. The residual value on the lease after 36 months, 12k miles per year, was only 53%, which was very low compared to Audi, BMW, Mercedes, Lexus. My buyout at the end is $30K.
I didn't care about those numbers as I intend to keep the car. I pay a bit more each month but less at buyout.
As has been said, the market will determine the price 3 years from now but consider this. Hyundai leasing needs to get $30K out of the car to make its numbers work. Hyundai dealers will be able to make a nice profit selling for $34k and the car will still have plenty of warranty left.
I think that's the minimum. Could be higher, depending on how the market goes and where the Genesis fits in against Audi, Lexus, etc. over the next 3 years. I seriously doubt it will be lower unless the opec can kill the frackers quick and get the price up fast. I don't see that happening.
