Can you get car insurance on a vehicle you don't own in Ohio?

My Jeep is having some issues with the heated seats. My mechanic thinks it could be a problem with the auxiliary battery. Where is the 2017 Jeep Grand Cherokee auxiliary battery location?

I think my car may be having an electrical problem (the headlights are dim and the battery light is on). Can I take it to a regular mechanic or do I need to find a special mechanic for electrical problems?

I’m looking for a good midsize luxury sedan from the 2010 era, and one of the vehicles that have come up in my research is the Audi A4 2.0T Quattro. I’d like to get the best value possible, so if I could get the oldest model there is, that’s what I want! What year was the first Audi A4 2.0T Quattro released?
