I know that something happened in the past concerning the owner and various message boards. I'm not sure what the details were, but I do remember reading a very long letter of apology that was posted on the boards from said owner.
I did months of research on car companies this last time (considering what we now refer to as "the Happy Limo incident") and in the end it was between two companies. So I did the email test...I sent them both a question and waited to see who answered first and how politely. XXX won that one hands down!
We used them last time and, unless reviews start getting bad, I will definitely use them again because I personally thought they were great! I know I emailed them twenty times to verify our ressies (OCD) and each time I got a super-fast answer that was extremely nice. The drivers were very nice and the whole thing couldn't have flowed more smoothly. The return driver did show up a few minutes late, but was sincerely apologetic, he took a wonder short-cut (without speeding) and ended up getting us to the airport sooner than if he would have been on time. The cars were clean and very well maintained (from all outward appearances). It was ten times better service than what we got from Happy Limo in 2004.
I know there is a new company that is getting rave reviews now and I'm watching the comments about them closely to see if they stay that way, but as of now, I still have every intention of booking with XXX again. But hey, that's just my opinion! Hope it helps!
