A used Mercedes W114 is a solid buy when the jacking points and floors are rust-free and the six-cylinder engine runs smoothly, because these cars hold up mechanically far better than their body metal does. Mercedes sold the W114 six-cylinder 250 and 280 models from 1968 to 1976 alongside the four-cylinder W115, as the Wikipedia W114 page covers. On Nov. 5, 2026, the NHTSA recall API returned zero campaigns for a 1972 Mercedes-Benz 280 query.
W114 or W115
The W114 is the six-cylinder car, and the W115 shares the body but uses four-cylinder gas and diesel engines. Sellers sometimes mix the two up. Check the model plate and the VIN. Coupes, including the 280C and 280CE, usually sell for more than sedans. Our Mercedes-Benz recall check guide covers how to run the VIN.
Rust at the jacking points
Check the jacking points, sills, floors, front wheel arches and the trunk floor. Rust at the jacking points is common and structural. Lift the carpets, look under the car, and look for fresh undercoating over patches.
Engine and fuel system
The six-cylinder engines are durable when maintained. Listen for timing chain noise, check for smoke and oil leaks, and confirm the fuel system idles smoothly when hot. Injected cars like the 280E need a specialist who knows the system.
Automatic gearbox, brakes and suspension
Most U.S. cars are automatics. Check for smooth, timely shifts and no slipping. Test the brakes for pulling, and listen for clunks from worn suspension bushes.
Service history and climate
W114s that lived in dry states usually have far less rust than cars from the snow belt. Look at the registration history by state, and ask for service records showing regular oil changes and timing chain checks. A car with a long history in one owner family and a folder of receipts is often the better buy. Air conditioning on these cars is often weak or converted; test it, and ask whether it has been changed to a newer refrigerant. A car that sat for years needs fresh fluids, hoses and tires before you drive it far. Ask for data plate photos too, since sedans and coupes differ in price and parts. Our odometer discrepancy guide covers mileage entries that do not line up.
When to walk away
- Rotten jacking points or floors.
- A W115 sold as a W114.
- Rough running that the seller cannot explain.
- A title number that does not match the car.
Questions to ask the seller
- Which model is this, by the data plate?
- Has rust been repaired, and where?
- When was the timing chain last checked?
- Has the title ever been branded?
Reading the history on a decades-old car
Do not expect a long service log. Records from the 1970s and 1980s were often never reported, so the report matters most for title brands, odometer readings at title transfers and registration gaps by state. A car that moved from a coastal or rust-belt state to a dry one may have been retitled; look at the dates and ask why. An approved NMVTIS check adds salvage and junk records from insurers and recyclers. If the odometer readings go backward or the car shows as exempt, ask for the paper trail before you price it. Our odometer discrepancy guide explains what those entries mean.
Private-sale paperwork
Most cars like this sell privately. Make sure the name on the title matches the seller ID, the VIN on the title matches the plate and the stamping on the car, and any old lien is released in writing. Our lien release guide walks through that step. Pay by a traceable method, get a dated bill of sale, and do not accept an open title signed by someone who is not present.
How to price it
Coupes, clean sedans and projects sell in different bands. Compare recent sales on Hagerty, and subtract rust work. Our E-Class guide covers the later cars if you want something newer.
What the report costs
As of early November 2026 a CARFAX bought direct usually costs around $44.99, and AutoCheck sits a little lower. We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Our guest price has been about $5.50 a report, about $4.50 for members, and about $6.75 for a CARFAX and AutoCheck bundle. Confirm the price at checkout, since it can change.
On a car this old, read the report for title brands and odometer readings first; service entries are often thin.
