By the way, what country are you in, and where do you go to get your Sai serviced?

Don’t plan on using snow tires to make the journey. Travel on your existing tires and then install the snow tires. You’d spend a significant % of that cost in extra gas.

[Another customer] I had a similar experience with an auto diagnostic person I really respected. He and his helper wired up my dashcam wrong (like, contrary to the manufacturer instructions which I gave them) and also wired up my rear fog lights so they depend on the headlights and not the front fog lights. When I went through the dashboard to troubleshoot, I found they also broke one of the plastic tabs on a part. Using a trim tool or just pulling the car manufacturer’s disassembly documentation would have averted breaking the part. I ended up losing respect and wondering if this is just the standard of service on offer, even from good people.

Why does everybody spell brakes wrong here?
