After recently getting my windshield tinted, I ended up replacing my Comma 3x with a Comma 4. Comma will give me $250 for it, but if anyone here wants to buy it for more than that, I'm happy to sell it to you, instead. It does not come with the necessary harness, ODB cable, or windshield mount, those will have to be purchased separately (links to what you need below). I have 20 days before the trade-in offer from Comma expires, so if no one's bought it by then, I'll be taking the $250. The 3x is in perfect condition, and worked great with my Gen 1 R1T using the harness from comma and no fuse tap or other auxiliary power.

The harness you need is either the Comma one, or one of the Xnor ones (Gen 1, Gen 2, Extreme Dev Kit; the extreme dev kit will give you longitudinal control and angle-based steering, but is currently a pre-order). If you get the harness from Comma, you'll also need their ODB-C cable (the Xnor harnesses come with one). You'll also need Comma's 8 degrees mount.
