Used MG B Buying Guide: Chrome Era, Recalls, Rust Checks

A used MG B is worth buying when the sills and floors are solid and the fuel-system recalls are sorted, because rot and fuel smell are the expensive surprises on these roadsters. MG built the B from 1962 to 1980, per Wikipedia, with U.S. cars shifting from chrome ends to the rubber-faced federal cars in the mid-1970s. On Nov. 5, 2026, the NHTSA recall API showed MGB campaigns including carburetor fuel-bowl screws that can loosen and seep gasoline (78V089000), a seat-belt webbing campaign (85V059000), missing certification labels or VIN plates on some cars (82V072000) and an electrical campaign on 1977-1978 cars (78V164000).

Chrome-era or federal rubber-era

Pre-1975 U.S. cars are the chrome-era look most people picture. From the mid-1970s, federal cars gained large black energy-absorbing ends, raised ride height and often a single Zenith-Stromberg carburetor instead of twin SUs. Wikipedia notes the GT coupe as well as the roadster. Neither is wrong, but they price differently and drive differently. Confirm the year with the VIN plate, not just the seller's ad copy. Our MG recall check page helps you start the VIN printout.

Recalls to clear

A loose fuel-bowl screw that seeps gasoline is a fire risk under the hood, so 78V089000 is the campaign I would insist on seeing addressed. The seat-belt campaign is easier to check in the cabin. Missing VIN or certification labels are a title and registration headache. Print the VIN results from NHTSA before you travel to see the car.

Rust and drivetrain checks

The classic MG B rot spots are the sills, floor pans, doglegs, rear spring hangers and the battery box. Lift the carpets. The B-series engine is simple and durable when oil changes were regular; listen for rod knock and look for oil leaks at the rear main. Gearboxes crunch second gear on many cars. Overdrive units need fluid and a working switch. Bring a pre-purchase inspection rather than trusting a driveway start.

Parts and ownership

Mechanical and body panels for the B are still widely sold, which is why so many of these cars survive. Soft tops, chrome and interior kits are easy to find. That also means a shiny car can hide a patched shell. Our service records gap guide is worth a read when the seller has few receipts.

When to walk away

• Rot through sills, floors or spring hangers.
• Fuel smell at the carburetor with no proof on 78V089000.
• A VIN plate that looks disturbed or does not match the title.
• A GT priced as a rare roadster, or the reverse, without paperwork.

Questions to ask the seller

• Is this a chrome-era or federal rubber-era car by VIN?
• Were the carburetor bowl screws and seat belts addressed under recall?
• Does the overdrive work in third and fourth?
• 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

Chrome-era roadsters usually bring more than late federal cars, and GTs sit in their own market. Compare recent sales of the same era, then subtract rust repair and an inspection.

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.
