If I could give zero stars, I definitely would!!! I started planning a family trip in May of 2018 for May of 2019. I called and reserved a 15 passenger van approximately 6 months (or more) before I needed it. When my husband and I arrived to pick it up, the employee took us to the oldest looking van on the lot. I really was not too concerned about that until we opened the doors and it had a musty smell in it and the seats and carpet looked stained and dirty. My husband asked the employee at that time if we could get a different van and he said the others were already reserved. My husband then asked if they are all 15 passenger vans, why couldn't he change out our van since we were already there and assign our van to someone else? The employee said the other 15 passengers cost more, that did not make sense to me and we found out later that was actually not true. We ended up taking the van they had assigned us because we had less than an hour before we had to pick up or children and grandchildren at the airport. Within 30 minutes after picking up the van and riding in it, I was more concerned about the musty smell. We were about to put or 5 grandchildren in this van, 2 of which are infants (all under age 5). The smell actually seemed to be getting worse, possibly due to the vents circulating the odor. About 30 minutes after picking up the van, I called back and asked for a manager. I spoke to Thomas and explained to him about the bad odor in the van and expressed my concerns about driving my grandbabies around in the van for 5 days and asked if I could exchange the van the next day. He was extremely rude from the very beginning of the conversation. He proceeded to raise his voice at me and said, "No ma'am, our vans absolutely do not have a bad smell!!" When I told him again that it did and that my husband smelled it also, he actually told me his nose was "trained" and he would know if it did. He also said he knew the exact van we had and that he had just sprayed it before we got it. I commented that it must have had a bad odor or he would not have sprayed it and he said they spray all the vans. He then said ALL vehicles have a slight odor due to the doors being closed all the time( again, the made no sense at all). The conversation lasted several minutes. He was rude and disrespectful the entire time and refused to exchange the van. We had no choice but to just keep it. Later that day, we realized there was something wrong with the air conditioning in the van. It would blow cool for about 2-3 minutes, then blow warm for about 5 minutes, then back cool. It did that the entire time we had the van. Needless to say, that made our 5 days pretty miserable, as the temperatures reached the 90's each day. When we returned the van, I explained to the young man everything that had transpired. He was very apologetic about the odor and the air issues. He also told us that all the 15 passenger vans are the same price. I wish I had that young man's name. Thomas should demote himself and make that young man the manager. Lastly, we were charged airport taxes even though we did not fly in. That is definitely not fair! I WILL NEVER RENT FROM CARL'S VAN RENTAL AGAIN AND I DO NOT RECOMMEND THEM TO ANYONE!!! ZERO STARS!!!
