What might stop you from starting.

Do I need experience flipping cars?

No. Redline is built to support beginners. You paste a listing, enter the costs you can see, and Redline shows the estimated margin, max buy price, and risk in plain language.

How does Redline analyze a listing?

It pulls the key details from the listing you provide, then estimates resale value, repairs, taxes, fees, and other costs you enter to calculate profit, ROI, and a recommended max buy price.

Does Redline guarantee I'll make money?

No. All resale prices, cost estimates, ROI, and profit projections are decision-support estimates, not guarantees. Results depend on market conditions, the actual car condition, and your execution.

What kind of listings can I analyze?

Any used car listing you can link to or describe — local marketplaces, dealer sites, and private listings. You adjust the inputs to match your market and the specific car.

How accurate are the estimates?

Estimates are a starting point based on the listing and your cost inputs. They're only as good as the information provided, so you should always verify the car in person before buying.

Can I save deals and compare them?

Yes. You can save analyzed listings, rank them by estimated profit, and compare them before deciding which one to pursue.

How does the negotiation assistant work?

After the analysis, Redline suggests an opening offer, a target price, and a walk-away number based on the estimated costs and your target margin.
