Quite good.

It's okay, there were three people handling the process which sped things up.

We booked a Dodge-type vehicle but got a Hyundai MPV instead. The car was equally spacious, accommodating 4 people and 5 suitcases. When we found out the trunk couldn't fit all the luggage, we folded down the third row, which created plenty of space. During the trip, there was a small incident where we missed booking an extra room for one night. We realized the trunk area was large enough for one person to sleep. Listening to the rain and train at night, I had a particularly good sleep. The car was new, only driven for 4000 miles, just past the break-in period, with strong power. No issues arose during the trip.

When I book the rental I don't need and upgrade

Like: Thrifty was efficient and the car was clean and good quality.
Dislike: There was no help with luggage in and out of the car.
