I've switched to renting cars for large mile trips. Unlimited mileage rentals are so cheap it's worth it to avoid wear and tear even on my older car or my girlfriend's nicer vehicle--and removes the risk of my old car breaking down in an inconvenient place. Last rental was an SUV for $65/week that I put hundreds of miles on. Some of the rentals I have put 1k+ miles on for <$100.

how the heck did you get $65/week? is that without insurance coverage for the rental?

Yeah, no insurance. I use primary coverage through a premium credit card, which covers damage/theft, towing, and loss-of-use charges.

There was a status upgrade involved and an online coupon code.
