Handicapped Accessible Limo

Ok here's the million dollar quesion...who offers a handicapped accessible vehicle? One of our groomsmen is in a motorized wheelchair so it can't be folded up and put into the trunk.

I've been told we can find a 55 passenger bus which is RIDICULOUS, we aren't heading down to Atlantic City for the day. The other option we've been given is an ambulette which, not to be a snob but, who the hell wants to ride in an ambulette in a bridal party?

I feel bad for this kid because he's so limited to begin with, the last thing I want is something that sticks out like a sore thumb, which I personally think will make him feel uncomfortable.

Isn't there anyone out there with a party bus that has some kind of lift? Or even a trolley that has a ramp? PLEASE HELP!!
