CarMax's ledger entry is short because the company's promises are unusually legible: fixed pricing, a 30-day/1,500-mile money-back window, a 90-day/4,000-mile limited warranty, and a retail lot policy that excludes salvage and frame-damage vehicles. Our file notes:
- The guarantee terms live on the buyer's order — verify the current numbers there, since programs evolve.
- Extended service plans are optional and priced like profit centers; decline or negotiate elsewhere if the math fails.
- Their appraisal offers are wholesale-anchored; treat them as a floor for your trade-in, not the market.
Verdict: the clearest disclosure regime in used-car retail. You pay for it in the sticker.
