Not sure what the budget is as F50's are going for sub $5m for an old one to over $12m for a later aircraft, but how about the CL300, Hawker 900XP or - if you are prepared to wait for them coming on to the second hand market - Hawker 4000? All of them will should do New York with one stop. La Mole is marginal at the best of times - if you can afford a $5m jet then the €750 transfer to your own pad in St Tropez is small fry!
