Dial 7 is your standard car service. clean cars and drivers. Limores is a slightl upgrade. the online system they have makes it easier to arrange the pick up and assures for not human error in info. Both times I have used them I was in brand new cars, Lincoln Nav & Mercedes. and the drivers were good. The cost was about 15% more...was it worth it to me? sure as I wasn't paying but if it were my own dime and I just wanted a good clean service I'd go Dial7 and save the 12 bucks each way.
