Why cost per remaining mile matters more than price

When you're shopping for a used car, the sticker price is almost meaningless without context. A $10,000 car with 140,000 miles on a platform that tops out at 160,000 miles has almost no remaining value. A $14,000 car with 70,000 miles on a Honda or Toyota platform that routinely hits 250,000 miles has 180,000 miles of life left — and costs under 8 cents per remaining mile. The more expensive car is the better deal by a wide margin.

The formula is simple: divide the asking price by expected remaining miles (typical lifespan for that generation minus current odometer). Compare that number across every car you're considering. It cuts through the noise immediately.

The generation problem — why year matters as much as make

Most people know that Honda and Toyota are reliable. Far fewer know that reliability varies sharply by generation within the same model. The Honda Accord is famous for longevity — but the 6-cylinder in the 2008–2012 generation had a known timing chain tensioner issue and transmission concerns that the 4-cylinder in the same generation didn't share. The 2013–2017 Accord 4-cylinder is a step up again. Buying blindly within a brand without checking the specific generation is how people end up with expensive surprises.

The Reliability Lookup tab above encodes this generation-level research so you don't have to watch hours of YouTube to find it.

New vs used — the numbers

New cars depreciate roughly 15–25% in the first year and up to 50% by year five. Buying a 3-year-old vehicle in good condition lets the original owner absorb the steepest part of that curve. For a $35,000 new vehicle, you might find the same car at 36,000 miles for $22,000–$24,000 — saving $11,000–$13,000 while still having most of its useful life remaining.

The calculus changes if you plan to keep the car 10+ years and drive high mileage annually, or if factory warranty coverage is important to you. For most buyers though, a 2–5 year old reliable Japanese make at 30,000–80,000 miles is the sweet spot of value.

What to look for at inspection

No matter how good the generation's reputation, always get a pre-purchase inspection from an independent mechanic (not the seller's shop) before buying. A $100–$150 inspection can surface $3,000 problems. Key things to check: oil condition and consumption, transmission fluid color and smell, coolant condition, timing belt or chain service history (on interference engines, a missed belt is catastrophic), rust on frame and undercarriage, and any stored diagnostic trouble codes. Ask for maintenance records — a seller who kept records is a seller who cared about the car.

Frequently Asked Questions

How do I calculate the true value of a used car?
Divide the asking price by the expected remaining miles (that generation's typical lifespan minus current odometer). This gives cost per remaining mile — a far better number than price alone. A $12,000 car with 80,000 miles on a 250,000-mile platform has 170,000 miles left: about 7 cents per mile. A $9,000 car with 140,000 miles on the same platform has 110,000 left — about 8 cents per mile. The cheaper car is actually worse value.
What mileage is too high for a used car?
It depends entirely on the make, model, and generation. A well-maintained Toyota Camry or Honda Accord from a reliable generation can be a great buy at 150,000 miles — they routinely reach 250,000+. The same mileage on a Nissan with CVT transmission or a pre-2017 Hyundai engine is much higher risk. Use the Reliability Lookup to check what's normal for your specific vehicle before deciding.
Which used cars are most reliable?
Consistently high long-term reliability comes from Toyota (Camry, Corolla, Tacoma, 4Runner), Honda (Civic, Accord, CR-V), Lexus (ES, RX, GX), and Mazda (Mazda3, CX-5). These brands have documented track records of 200,000–300,000+ miles with proper maintenance. Subaru is reliable but some engines have head gasket issues at high mileage. Hyundai and Kia improved dramatically after 2017 but older generations had serious engine recall problems.
Should I buy new or used?
New cars lose 15–25% of value in year one and up to 50% by year five. Buying a 2–4 year old used car in good condition lets someone else absorb that depreciation. For reliable makes like Toyota and Honda, a well-maintained used car at 40,000–80,000 miles typically offers the best combination of remaining life, lower price, and known reliability history. New makes sense if full warranty coverage or specific features matter more than price.
How many miles does a Honda Accord last?
A well-maintained Honda Accord from a reliable generation routinely reaches 200,000–300,000 miles. The 4-cylinder engine is generally more reliable than the V6 in most generations. Regular oil changes and timing belt service (on applicable engines) are the critical maintenance items. The 7th gen (2003–2007) and 9th gen (2013–2017) 4-cylinder are especially well-regarded for longevity.
What is the sweet spot mileage for a used car?
Generally 40,000–80,000 miles for most reliable makes. At this point the new-car depreciation is fully absorbed, but the vehicle still has most of its useful life ahead. For Japanese makes with 200,000+ mile lifespans, even 100,000–120,000 miles can represent excellent value if the price reflects it appropriately and the maintenance history is clean.
