Three biggest factors were garage space, styling, performance. I'm coming from a line of smaller vehicles ('06 Evo, '08 STi, '12 135i, '16 340i), but now our family is growing and I need something a bit bigger. I also like the proportions of the Explorer ST over the expedition. Dream car would be a wagon (E63 AMG, RS6) but price is always a factor.
I might lower the ST (only 1.125"), and I didn't order it with roof rails in hopes to keep it more 'wagony' looking and less upright SUV.
