Rideflex is now Roadrunner Limo. I'm not sure which came first or if Roadrunner acquired Rideflex.\n\nI use this car service because it's substantially cheaper than other car service companies: $71 to PHX Sky Harbor versus like $90+ from other companies I received quotes from. I have an account with Roadrunner and use them on a regular basis when I travel. \n\nThey are never late which is awesome and always super polite. The cars are hit or miss: some are gorgeous and new and black and shiny and others kind of seem like taxi-cabs -- the lack of beautiful cars bothers me about Roadrunner. However, I do realize the price difference. \n\nSome of the drivers can be annoying and super chatty. I'm not really confrontational so I never ask them to be quiet. There are little luxurious missing like bottles of water.\n\nSometimes I've requested a towncar and the driver has showed up in a SUV. The driver told me it was a \"complimentary upgrade\" but the SUVs aren't nearly as comfortable as the towncars.  \n\nI will continue to use them based on price but I'd might consider upgrading to a new company when I feel okay spending more money.
