Before You Sign: A New-Car Checklist

1. Confirm the exact car, down to the trim

It sounds obvious, but mix-ups happen more often than you'd think. Two vehicles of the same model can look nearly identical on the lot and still differ in trim, drivetrain, and packages. Before anything else, match the VIN on the paperwork to the one on the windshield and the driver's door jamb.

Ask to see the window sticker, also called the Monroney label. It shows the factory equipment and the manufacturer's suggested retail price. Think of it as your reference for what's actually on this car, as opposed to the one you happened to drive last weekend.

Quick things to match:

• Trim level and drivetrain, such as front-wheel or all-wheel drive
• Exterior and interior color
• Factory packages and options
• Any dealer-installed accessories, which usually appear on a separate addendum sticker

If you're still deciding, browse our new inventory online before you visit. Narrowing it down at home means the car you sign for is the one you meant to buy, not the closest match that happened to be parked out front.

2. Set your budget by total cost, not the monthly payment

Most people walk in with a monthly number in mind. That's natural, but almost any payment can be made to fit by stretching the loan term. A longer term usually means more interest over the life of the loan.

Think in terms of the out-the-door price. That's the vehicle price plus sales tax, title and registration, the documentation fee, and any add-ons, minus your down payment, trade value, and rebates. In New York, sales tax is based on where the car will be registered, so your home address affects the final total.

Costs that show up after you drive away

Insurance is the big one. Call your agent with the VIN, or at least the exact trim, before you sign, because rates can shift noticeably between trims and drivetrains. Budget for fuel, routine maintenance, and eventually tires too.

Here's a simple gut check: if the payment only works at the longest term on offer, the car may be a stretch. Better to learn that over coffee at home than across a desk.

3. Drive the car the way you'll actually use it

A loop around the block tells you very little. If your commute runs along Route 58 or out the Long Island Expressway, ask to include a stretch of highway. You'll hear the wind and road noise and feel how the car merges.

Bring whatever you'd normally carry. Car seats, a stroller, golf clubs, the dog's crate: see if they fit. Sit in the back seat, not just behind the wheel, and check your view over your shoulder.

Things to try while you're in it:

• Pair your phone and test the infotainment and voice controls
• Adjust the seats and mirrors for every regular driver in your household
• Try the driver-assistance features you'd be paying for
• Park it, including backing into a tight space

If two trims are close, drive both back to back. Differences in seat comfort, ride quality, or cabin quiet are much easier to notice when the first drive is still fresh. You're going to live with this car for years, so a little extra time now is well spent.

4. Know your trade-in's value before you negotiate

Your current car is part of the deal, and it's easy to lose track of. Get a sense of its value from a couple of independent sources. Gather the title or your loan details, both keys, and any service records, since a well-kept history can help.

Keep the trade separate in your head from the new-car price. A generous trade number means little if the purchase price crept up to match. Look at each one on its own, then at the net difference you'll actually pay.

If you still owe money

Ask your lender for a payoff amount that's good through a specific date. If you owe more than the car is worth, that negative equity gets rolled into the new loan unless you pay it down. It's legal and common, but it raises the amount you're financing, so see it in writing before you agree.

You can value your trade online before visiting. It won't replace an in-person appraisal, but it gives you a realistic starting point for the conversation.

5. Find out which offers apply to you

Manufacturer incentives change often and come with eligibility rules. Some are cash rebates, some are special financing rates, and others are lease deals. You usually can't stack them all.

Ask which offers apply to the exact vehicle you're buying, and whether choosing one rules out another. A low promotional rate, for example, may replace a cash rebate rather than add to it. Promotional rates also typically require qualifying credit, so don't count on one until the lender decides.

Check the expiration date too. If you're shopping near the end of the month, an offer may end before your paperwork is finished. Looking at our current offers before your visit shows you what's available right now.

Programs worth asking about, since they're sometimes available:

• Recent college graduate offers
• Military or first-responder offers
• Loyalty offers for current owners of the same brand

Make sure any offer you were promised shows up as its own line on the buyer's order. If it isn't written down, it isn't part of the deal.

6. Line up your financing questions in advance

A preapproval from your bank or credit union before you shop gives you a rate to compare against. It isn't a commitment. What it does is put you in a clearer position when the dealership presents its own financing options.

Know your credit score going in. Approval and rates depend on your credit history and each lender's decision. Nobody can honestly promise a particular rate before you apply, so be cautious of anyone who does.

Questions to ask about any loan

• What's the APR, not just the payment?
• How many months is the term?
• Is there a penalty for paying it off early?
• What's the total amount paid over the life of the loan?

You can explore financing through our dealership and compare it side by side with your outside offer. Choose whichever works better for your situation. A slightly lower payment on a longer term may cost more overall, and the total-paid number from that last question is what reveals it.

7. Read the buyer's order line by line

This is the document that matters most, and it's where rushed buyers miss things. Read it line by line, and ask about any charge you don't recognize. A good salesperson should explain it without hesitation.

Look closely at:

• Vehicle price and any dealer-added accessories
• Documentation fee, which New York caps by law
• Sales tax, title, and registration
• Trade-in value and loan payoff
• Rebates and your down payment

Optional products

In the finance office you'll likely be offered extended service contracts, GAP coverage, tire-and-wheel protection, or appearance packages. Some can be worth it depending on how long you'll keep the car and how you drive. They're optional, though, and you can decline them or ask for time to think.

One last check: make sure nothing you turned down ended up on the contract anyway. Usually it's an honest mistake, but you're the one paying for it if it slips through, so catch it before signing rather than after.

8. Inspect the car before you take the keys

Delivery day is exciting, which is exactly why this step gets skipped. Do a slow walk-around in good light. Look for scratches, paint chips, or small dings from transport or time on the lot.

Before you leave, confirm:

• Two key fobs, since a replacement can be costly
• Floor mats, cargo cover, and any accessories you paid for
• Owner's manual and warranty booklet
• A reasonable amount of fuel
• Your phone paired and any connected-services app set up

If something needs fixing, get a written due bill, sometimes called a 'we owe' form. It should spell out exactly what will be done and when. Verbal promises are easy to forget on both sides.

While you're there, ask when the first maintenance visit is due and what it includes. At Riverhead Nissan, service ranges from basic tune-ups to major mechanical work, and you can book service online when the time comes. Knowing who you'll call for that first oil change takes one more question off your list.
