Used Plymouth Conquest Buying Guide: Turbo, Rust and Belts

A used Plymouth Conquest is worth buying when the turbo engine is healthy, the body is solid and the 1986 seat-belt buckle recall has been addressed on covered cars, because these Starion twins are expensive to restore wrong. Chrysler sold the Conquest as a captive import in the mid-1980s, as the Wikipedia Starion / Conquest coverage outlines. On Nov. 5, 2026, the NHTSA recall API returned one campaign for a 1986 Plymouth Conquest query: 95V103003, front safety-belt buckle release buttons that can break.

Prove the Conquest identity

Match the title and dash plate to a Conquest, not a random Starion badge story. The cars share bones; the paperwork should still match what you are paying for. Our Starion guide covers the Mitsubishi twin.

Turbo engine and cooling

Check for oil leaks, boost behavior, smoke and a recent timing-belt service where applicable. Watch the temperature gauge in traffic. Ask for receipts on the turbo, radiator and fuel system.

Seat-belt buckle recall

For 1986 cars, ask whether the 95V103003 buckle release buttons were replaced. A broken red PRESS button is a reason to pause until the hardware is fixed. Run the VIN on the NHTSA recall lookup either way.

Rust, electrics and paperwork

Check the sills, floors and arches. Try every switch and gauge. Match the title VIN to the plate. Our Chrysler Conquest guide and Mitsubishi recall check guide cover related lookups.

Conquest vs Starion badge

The Plymouth Conquest is a Mitsubishi Starion twin sold through Chrysler dealers. Confirm the plate and title say Conquest if that is what you are paying for, and do not treat a badge swap as a different car. Parts overlap with Starion catalogs, which helps, but turbo and electronics work still add up. Ask for boost-gauge behavior on a hot restart and for proof of a recent fuel-system service. Our Starion buying guide and our Chrysler Conquest guide cover the related badges. A clean, stock example usually beats a half-finished turbo project at the same price.

When to walk away

• A broken seat-belt buckle release on a covered year.
• A noisy bottom end or a smoking turbo.
• Heavy structural rust.
• A title number that does not match the car.

Questions to ask the seller

• Was the 95V103003 buckle work done?
• When was the timing belt last done?
• Has rust been repaired in the sills?
• 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

Clean Conquests sit near Starion money when original. Compare recent sales on Hagerty, then subtract turbo and rust work.

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.
