Handing your keys to a stranger is the part of selling that makes most owners nervous, and they're right to be. A test drive is where a sale gets made, and it's also where a fender gets bent, a clutch gets cooked, or a car leaves the driveway and doesn't come back. None of that is common. All of it has happened to somebody who skipped a step.

The good news is that a test drive selling classic car owners can run safely isn't complicated. It takes a little screening on the phone, a few minutes with your insurance agent, a route you picked ahead of time, and the discipline to stay in the passenger seat. This piece sticks to the drive itself. If you want the whole process from prep to payment, start with how to sell a classic car and come back here when the phone starts ringing.

Before anybody gets behind the wheel

Screen buyers before they show up. A five-minute phone call tells you most of what you need. A real buyer asks about the car: how it starts cold, what's been done to it, whether the gauges work. A joyrider asks what it'll do and whether he can bring his buddies. If somebody won't talk on the phone and only wants to "come by and drive it," that's an answer too.

Then call your insurance agent, before the first showing, not after something goes wrong. Ask two plain questions. Is a prospective buyer covered when he drives my car with me in it? And are there limits that change when somebody else is driving? Most standard policies follow the car and cover a licensed driver you give permission to, but collector policies are written differently from a daily-driver policy. Some exclude drivers under 25, and all of them limit how the car can be used. You want to know the answer from your agent, in writing if you can get it, not from a guess.

When the buyer arrives, ask for his driver's license and take a clear photo of it with your phone. Ask for his insurance card too and photograph that. Text the photos to a friend or family member. A legitimate buyer won't mind. Most expect it. Anyone who argues about it has just saved you a test drive.

Plan the route and drive it first

Don't let the buyer pick the road. Pick it yourself, ahead of time, and drive it once so you know it. You want about fifteen or twenty minutes of mixed driving: a few stops and turns, a stretch where the car can get up to forty-five or fifty, and a place to pull over safely and look under the hood. Stay off the interstate and away from heavy traffic. An old car on bias-ply tires or drum brakes doesn't need a stranger learning its manners at seventy.

Start the car cold in front of the buyer if he asks. A serious buyer will ask, because a lot of sins hide in a warm engine. If you warmed it up an hour before he came, he'll notice, and he'll wonder why.

Then you drive first. Take the car out on your route with the buyer in the passenger seat. Show him how it starts, how the choke behaves, where the gears are, which gauge reads a little high and why. That's not a sales pitch. It's how you find out whether this person should be driving your car at all. If he's grabbing the dash at thirty miles an hour, the second half of the drive might be you driving him back.

Riding along: what you're actually watching

You ride along every time. No exceptions. Not around the block, not "real quick," not because he seems like a nice guy.

From the passenger seat, watch how he handles the car before you worry about what he thinks of it. Is he easing it into gear or slamming the shifter? Is he riding the clutch, or launching it from a stop sign to hear the exhaust? Is he braking early, the way you need to in a car built before power discs were standard? An old car tells you a lot about the driver in the first few blocks. You're allowed to say "let's head back" at any point, and you don't need a reason beyond your own judgment.

Keep your talk honest and short. If he asks about a noise, tell him what you know. If you don't know, say so. Don't fill the silence with sales talk. A buyer driving a classic is listening to the car, and that's what you want him doing.

"You can tell more about a buyer in the first three blocks than in an hour of talking. Watch his hands and his right foot. If either one makes you nervous, you've got your answer, and you didn't have to argue about it."

— Robert Halloran

When to say no, and how to end a drive

Some people shouldn't drive your car, and you get to decide who. Say no to anyone without a valid license, anyone who smells like a bar, anyone who shows up with a group and wants to pile in, and anyone who wants to take it out alone "to get a real feel for it." Say no to a buyer who hasn't asked a single question about the car's condition but wants to drive it hard. And say no if the weather turns, if it's getting dark, or if the car isn't right that day. A classic that runs rough on a cold, wet morning isn't a good look anyway.

Ending a drive early doesn't need to be a scene. "I'm going to take it from here" works fine. Pull over somewhere safe, swap seats, and drive back. If he's offended, he wasn't your buyer.

A buyer who's driven the car and wants a mechanic to look at it is a good sign, not a problem. Let him pick the shop, pay for the inspection, and set a time when you can drive the car there yourself or ride along. Don't hand over keys for an inspection you're not at.

After the drive: back in the driveway

When you get back, park it, take the keys, and check the odometer and the car. Then give the buyer a few minutes with it. Let him walk around, look underneath, open the hood again now that it's warm. That's often when the real questions come out, and it's when he's deciding whether this is his car.

Don't talk price in the driver's seat. Wait until you're both out of the car and he's had a chance to think. If he makes an offer, you don't have to answer on the spot. The way you handle what comes next has its own set of rules, and it's worth reading how to negotiate selling a classic before your first showing so the number doesn't catch you flat-footed.

And if he doesn't make an offer, that's fine too. Thank him, shake his hand, and let him go. Plenty of buyers drive two or three cars before they pick one. A test drive that went smoothly, with the car running right and you in control the whole way, is still the best thing you can do to sell it, even when the check comes from the next guy.
