Hey Kreig,
Congrats on getting the SR5! Have you tried out the sound system yet? A big reason for me leaning to the Sport is for the upgraded sound. If the SR5 has decent enough thumpin bass, then I could live with it.
Honestly from the reviews I’ve seen, the Sport Premium is a nice upgrade. From leather seats to the sound system. It’s definitely a step up in quality, but I just don’t like the rims lol.
