Been to bon lifts times
Rented from AB first time. Got the "you put a new dent (on the old dent routine) you owe us $x." First and only time, no new knowledge.
Rented from everts. Brand spanking new truck. No problems at all with the process except I spent the whole 2 weeks worrying about that damn truck. And the inspected with a fine toothed comb.
Both these were a long time ago - early 90s mAybe.
We settled on Telerin (Poppy) for many years. Trucks were usually beaters. Got one one year with s mesh tailgate - hated that. Thereafter i specified i wanted a truck with working tailgate and always got one. Never a problem with email/quotes, though I've seen reports of slow/no response. I've also heard, don't know, that she has upgraded her fleet. As far as what-you-think vs what-you-wind-up paying, alwAys an exact match to what I asked for. And the best pickup/drop off arrangement going. She was also one of the few to accept Amex if you wanted to use it for their insurance. We rented many times from her with never a hitch. The trucks were beaters so nobody cared or even checked for new scratches/dents on top of the old ones.
After a hiatus from bon for 4 years we're back now. We rented thru Back To Basic because our accommodation has an arrangement with them. Trucks are ok, semi beater but good tires. We were quoted a price without full insurance, and a $/day price for adding full. When doing the paperwork they asked if I wanted full, and added it to the bill. the bill was what I expected. Can't report on the return yet, but the whole deal seemed odd to me. Marco from BTB met us outside arrivals as normal, then we drove off the airport grounds to the area by the fence. He said they couldn't do business on airport property. Strange. We sat and did the paperwork, and I paid via credit card (5% upcharge), but that is not unusual on bon, though I don't remember it being disclosed. We're supposed to meet him Saturday at noon by the fence and be dropped off at the airport. All is well so far.
Except for the first time with AB we always get full insurance. If/when we return to bon we'll probably book with poppy, though nothing wrong with BTB thus far.
Obviously my info is very dated, but there ya go, our real-life experiences.
