I booked Executive Car Service for the bride and groom as the best man at a wedding. ECS was easy to book, and easier to make a change to the orginal reservation time when the need arose. Executive Car Service showed up on time with the cleanest sedans I've ever seen. The driver was friendly and professional. I highly recommend ECS for anyone looking for a sedan or limo service nationwide. I utilized their services in Dallas, but according to their website they have a presence in every major city nationwide including New York, Chicago, Baltimore, and L.A. - along with 600 other cities - they even have worldwide car service locations.
Pros: On time, Clean Car, Professional Service, Ease of Booking
