We Accept 21st Century
And Fight For Your Maximum Payout.
We work directly with 21st Century adjusters to maximize your claim, handle all paperwork, and restore your vehicle to factory condition. Nassau County’s trusted collision center for over 40 years — we know exactly what your 21st Century policy entitles you to.
You Don’t Have to Use 21st Century’s Preferred Shop
21st Century Insurance may recommend their approved network of body shops — but New York State law gives you the absolute right to choose any licensed repair facility. Our I-CAR Gold certified technicians work for you, not your insurer, fighting to maximize your 21st Century payout and restore your vehicle to factory specification.
NY State Law Protects Your Choice
You have the legal right to choose any licensed repair facility — 21st Century cannot force you to use their preferred shops.
We Work for You, Not 21st Century
Our team advocates for your maximum coverage — not the minimum payout that protects the insurer’s bottom line.

We know exactly how 21st Century’s claims process works and what your policy should cover — inside and out.
