Morgan 4/4 and Plus 4 (1950 to 2000)

Why people buy one

• A hand-built British sports car whose looks barely changed in decades, with a strong following and an active club.
• The engines are mainstream units from Standard-Triumph, Ford, Fiat and Rover, so most mechanical parts are easy to get.
• The Triumph-engined Plus 4 uses the same engines as the TR2 to TR4 sports cars, and the 2138cc TR4 unit is generally rated the best of them.
• The steel chassis and ash frame can be repaired or renewed, and Morgan still supplies many body and chassis parts.
• The factory archive can issue a Chassis Record Certificate, so a car's original specification can be checked.

What to weigh up

• The ride from the sliding-pillar front suspension is firm and jouncy, the cabin is tight, and the hood is slow to raise and not fully watertight.
• Hidden ash-frame rot and chassis rust are common; Sports Car Market warns that cars that look sound can turn into major projects.
• Identity needs checking: Plus 4s came with Vanguard, TR2, TR3 and TR4 engines, and a claimed Super Sports (a small run from 1961 or 1962 with Lawrence-tuned TR engines and a low-line aluminium body; published totals range from about 95 to just over 100) should be backed by a factory record.
• Engines have often been swapped, and Classics World says even Morgan may not know the exact specification of some early 1970s cars built with a mix of parts.
• The Moss gearbox in the Triumph-engined Plus 4 has no synchromesh on first, and parts and rebuild knowledge are scarce.
• This profile does not cover the glassfibre Plus 4 Plus coupe (26 built), the Plus 8, or 4/4 and Plus 4 models built after 2000.

Where they rust

• The ash frame, especially the hinge posts and the wooden sill boards under each door; a hinge post that moves with the door open points to rot.
• The steel chassis rails and crossmembers, which had little rust protection before the mid-1980s.
• The front valance (flitch panel), which is double-skinned near the steering column and traps water, and the joint where it meets the bulkhead.
• The scuttle and cowl, and the bulkhead where it meets the wings; Sports Car Market reports terminal rust in cowls and firewalls.
• Wing edges, where steel strips and brackets react with aluminium, and the rear corners of the rear wings.
• Behind the wings on pre-1986 cars, where paint cracks at the beading let water in.
• Paint blisters around the headlamp pods, wing lamp bolts and lower door corners.

Mechanical weak spots

• The engines are mainstream Ford, Fiat, Rover and Triumph units, so their faults and fixes are well known; check for smoke, oil leaks and rattles as on the donor cars.
• The sliding pillars need regular lubrication; most cars have a one-shot oiler worked from the cockpit, and kingpins and bushes wear out faster if this is neglected.
• Most cars in this period use a steering box rather than a rack; excess play means wear, and heavy steering can mean dry or worn joints.
• Front disc brakes were an option on the Plus 4 from 1959 and standard from 1960.
• Electrics are simple; check that the lights, gauges and wipers work.

At a Mathewsons viewing

• Find the chassis number (on older cars it is stamped on the crossmember behind the seats or on a plate on the bulkhead) and check it against the V5C; ask whether the car has a Morgan Chassis Record Certificate.
• Read the engine number and type and compare them with the V5C and the record: a Vanguard, TR or later engine should match what the seller claims for the model and year.
• Open each door and press the hinge posts and sill boards for softness, and check that the doors close cleanly without lifting.
• With a torch, look under the car at the chassis rails, crossmembers and suspension mounts, and for rust where the bulkhead meets the valance.
• Lift the carpets and check the floorboards and footwells for damp, and if staff start the car, listen for knocks and rattles and watch the oil pressure; do not assume it will be started.
