What are the best interior accessories for a new Dodge Challenger?

^ This. Also, if you're worried about spills on that road trip, the WeatherTech FloorLiner DigitalFit Black is basically the industry standard for a reason. They use laser measurements so the edges actually meet the trim, which prevents coffee or mud from seeping under the pedal area. Lloyds look nice but they wont hold a puddle if you drop a drink. Regarding the camera, waiting for a high-end unit is risky if you're hitting the road next week. A decent mid-range option like the Vantrue N2 Pro Dual Dash Cam fits your 300 dollar budget perfectly alongside the mats. It is better to have solid proof in an accident now than nothing at all while you save up for a Blackvue later. It just works better for your immediate safety needs. TL;DR: prioritize the laser-cut liners for spill protection and grab a solid mid-range cam to stay within budget while staying protected.

I definitely agree that floor protection should be your top priority. Honestly, cleaning gunk out of brand new carpet is a total pain. You might want to consider:

• Rubber liners first because they handle liquid displacement better.
• Checking the polymer density to ensure they dont curl over time. Be careful with those plush mats tho, they look cool but wont stop a soda leak, ngl.
