Platinum because it has features you specifically want. Sell the monster wheels it comes with for something that ride and look better. A friend if mine picked up an MKZ w massage seats. They're pretty slick. If I was dropping 70k+ on a truck I'd probably go all out and get anything and everything I wanted.
Not sure why anyone cares what you're doing w equity in the 18. Obviously you realize you're throwing $ in a bonfire but if its what you want, go for it. I'm all for people making spontaneous purchases like these, it frees up inventory for something I could potentially buy. Picked up a few nice things over the years where someone was just tired of what they had or wanted a different experience.
Is the 2018 that loud? I drive an 03 and its pretty quiet up until about 65-70mph and you get wind/road noise but nothing crazy. My parents 2018 Camry is louder on the hwy than the expy. In town and low speeds mine extremely quiet, radio set on 6 or 7 out clearly audible.
concurrence!
