Jensen Interceptor and FF (1966 to 1976)
By Jon Cosson · Last checked
The Jensen Interceptor (1966 to 1976) is a Chrysler V8 grand tourer with an Italian-styled steel body; the FF is its four-wheel-drive sister. Rust and FF identity checks matter most. The 541, C-V8 and later revivals are not covered.

Why people buy one
- A big, fast, comfortable GT with a Touring-designed body and a large glass tailgate.
- The Chrysler V8 and TorqueFlite automatic are robust and mechanical parts are widely available.
- The FF was a pioneer, combining Ferguson four-wheel drive with Dunlop Maxaret anti-lock brakes in a production road car.
- Convertibles and the rare SP and coupe add variety.
- The Jensen Owners' Club, founded in 1971, covers all Jensen models and offers technical help.
What to weigh up
- Rust is the main problem, and a full restoration is a major undertaking.
- Fuel consumption is high, around 10 to 13mpg.
- FF identity: only 320 FFs were built (195 Mk I, 110 Mk II, 15 Mk III), so check that a claimed FF has the correct chassis code and four-wheel-drive system.
- Sources disagree on production totals: 6,408 or 7,141 Interceptors in all, with 267 or 456 convertibles and about 46 to 60 coupes.
- The Series 4 Interceptor (built in small numbers from the mid-1980s to 1993) and modern re-engineered cars from companies such as Jensen International Automotive, which use an original car with a GM V8, are not covered here; check which a car is.
- Dashboard trim is hard to replace, and a full retrim is a major job.
Where they rust
- Inner and outer sills, which are structural and trap water.
- Side beams and outriggers alongside the main chassis rails.
- Floors and footwells.
- Front and rear wheelarches.
- Front and rear valances.
- Windscreen surround and the roof; roof corrosion is a serious warning sign.
- The glass tailgate surround and hinge area.
- Areas where lead loading was used during manufacture; check for bubbling.
Mechanical weak spots
- Engine: minor oil leaks are common; oil pressure should be 30 to 40psi at idle. Clogged hydraulic tappets can cause uneven running, and sump debris can block the oil pump.
- Cooling: watch closely for overheating, which is common in traffic.
- Gearbox: the TorqueFlite three-speed automatic is strong; check fluid colour and level. Only a couple of dozen early cars had a four-speed manual.
- Rear axle: Powr-Lok limited-slip differential; leaf springs often sag.
- FF: check the Ferguson transfer box, front differential and Maxaret anti-lock system; these are specialist items.
- Brakes: discs all round, ventilated on later cars; check pipes and hoses.
- Electrics: wiring can become brittle with heat, and Hagerty notes a history of electrical fires; look for burnt connectors and oversized aftermarket batteries.
At a Mathewsons viewing
- Find the chassis plate (Sports Car Market gives the inner wing or door post, with the number also stamped on the front crossmember) and check it against the V5C. FF numbers carry a model code before the serial: 119 for the Mk I, 127 for the Mk II and 130 for the Mk III.
- To check an FF, look for two diagonal vents behind each front wheel (one on the Interceptor) and a longer front wing and wheelbase, and look under the car with a torch for a front differential and propshaft.
- Lift the carpets and check the floors and footwells, and with a torch look along the sills and side beams for rust or filler.
- Open the tailgate and check the release cable works and the surround is sound, and look at the roof and windscreen surround for bubbling paint.
- Open the bonnet and look for oil and coolant leaks and brittle wiring, and if staff start the car, listen for tappet noise and watch the oil pressure; do not assume it will be started.
Parts, specialists and clubs
Mechanical parts for the Chrysler V8 and TorqueFlite are widely available, and some UK suppliers still have access to Jensen's original presses for panels. Some trim, such as the dashboard, and FF four-wheel-drive parts are scarcer. The Jensen Owners' Club covers all models and offers technical help.
