Sorry I missed your request, hope you had a god trip!
We live near Playa and are in the process of getting our permanent visa so we are still renting, right now for 6 - 8 weeks at a time.

We have used America a lot over the years, best price point (IF you use the "MXN" pesos currency when booking, otherwise not a great price) and decent service. We've also used Avant with just mediocre service and a terrible vehicle. We only used them because they used to meet you at the airport terminal. They no longer do, but their price point is still high. America also does not deliver the vehicle to the airport terminal So if you want that convenience - whether you have several bags or people - ISIS out of Playa does meet you at the terminal. Edgar's price is a little higher and is more in-line with Avant. but he will negotiate with you, and if you pay in pesos the price will be substantially lower. But the service and support is sooo much better than the others.
Note for others - do not stop in the timeshare alley when departing the terminal - don't stop until you are outdoors. The America and other reps will be straight ahead by the curb near the Margaritaville bar.
All of these outfits include insurance in their quote. Don't rely solely on the online pricing with smaller outfits like ISIS - request a quote as the price can fluctuate depending on inventory.
