I had the best rental experience I’ve ever had with sixt. No unexpected fees. No crazy insurance surprises. The woman who helped me and the counter, Lynn, did everything she could to make my rental perfect for what I needed.
Overall it was fine. However, picking up the car was slow and painful. Most everyone had to wait 45-60mins + to receive their car after you paid and went thru customer service rep. The van we got was new but had some obvious minor damage all around. 10 minutes into the drive from Budget and the front right TPS (tire pressure sensor) was alarming that there was an issue. Luckily, the tire was fine and just a bad sensor but was a bit annoying getting that warning everytime you started the van. Overall, it was worth it. Just need some patience at the start.

They gave me an old car making funny noise over 40 mph. There was a super long line with exactly 2 agents behind the counter who happen to be less than friendly, trying to aggressively push for things I did not want nor need. Return procedure had no explanations and when I sought to ask, they were very rude and could not be bothered. Probably the worst rental car experience overall I ever had.
They didn't do a walk around of the car. There were scratches prior to my pick up, which made me anxious that I would get charged for something I didn't do. I think Hertz should be doing an inspection of the vehicle prior to hand off
Took forever to get car. Had flat tire on top of Waimea canyon. Tire was bald and no owners manual to help figure out where spare tire was. Waited 2 hrs and still no tow truck. Finally found someone with same vehicle and looked at owners manual regarding spare tire. We would appreciate a partial reimbursement for our terrible day!!

Easy process when actually picking up our car and when returning. Great people at the rental, so friendly and helpful.
Did not get original car reserved - Medium sized SUV. I was given instead a Minivan. I had to back to counter to correct mistake which took over an hour:(
