Due to crashes in the past and especially the 2018 crash near Albany, NY that killed 20 people, NY regulations are soo tight for stretch limousines- many companies have removed them from the fleets.
Most Companies have chosen to do sedan, SUV, sprinter vans, party buses, mini buses, and coach buses to bypass the issues with getting state approve for the stretch vehicles.
Link for information on accident mentioned:
We have found that with our fleet of sedans and SUVs, it suits us with the needs of those that call upon us.
When we have a request for bigger vehicles, we explain that we do not offer bigger and will try to offer multiple vehicles to accommodate the request best we can.
We do have friends in the industry with the bigger vehicles which we trust and will refer to them as needed.
