We once used them, although it was inadvertent! Normally we use Happy Limo, but one night we were having someone we know pick us up instead. To make a long story short, they did not show and we couldn't reach them. There was a Mears towncar driver waiting for a party who did not show up...since we were all in the same boat (or I guess that would be opposite boats), we ended up going with him instead of a cab. The towncar was nice and clean, and he was courteous; he did end up getting lost, but in all fairness we were going to a confusing destination and there was no way he would know due to the spontaneous nature of our hiring him. All in all, it was not a bad experience; better than a cab.
