I've used PenFed for my last five cars and have always had a great experience. The car comes in, you agree on price, go home later that day to let PenFed know the financing amount and they overnight a check for next day delivery. Such an easy experience.
However, since this is a new model they'll need to update their database which may take time as it did when I financed my 1M. They had no idea what a 1M was back then so I had to take them to ///M skool.
