Yes, there's always Uber. But sometimes you need more 'dedicated', private vehicle, that you would consider 'yours' for the time of your stay in New York City or in US. And, of course, with a dedicated private driver, God forbid you drive in NYC - there are cities with worse traffic-drivers-roads combination in the world (maybe), but there are no such city on this planet where you can't physically leave your car on the street for the reason of total absence of not even parking, but simply legal standing spots. So, you need to be driven around in the comfort of your 'temporary own' car with 'your' dedicated and experienced driver. And... here's where we can help!
Whether you need to go for the school or University visit, or simply have your child be driven from somewhere in Massachusetts to NYC, or you had an urge for the whole day shopping in an outlet mall, or your company wants you to go for the farms/stores/hotels check - we got you covered. 
It could be a limo, a stretch limo, a van, or an SUV - we have them all for any taste and budget.
