Rust and bodywork

Two features of the E-Type's construction decide how it corrodes. The centre of the car is a monocoque, so the body is the structure and there is no separate chassis to fall back on. The engine and front suspension hang from a bolted-on framework of smaller tubes and pressings ahead of the bulkhead. Rust attacks both, but it attacks them differently, and the remedies differ too.

The monocoque: floors, sills and boxes

Water gets in around the screen seals, the door apertures and the rear of the cabin, and it leaves slowly. It collects in the sills, which on an E-Type are structural, and in the box sections and floors that tie the shell together. From inside, the early signs are under the carpets and sound deadening rather than on the visible surface, so a check that stops at the door bottoms has not really started.

At the back, the boot floor, the spare wheel well, the rear wheel arches and the area around the rear suspension cage are the classic homes for rot. The independent rear suspension hangs in its own cage and its loads feed into the shell nearby, so corrosion there is not only cosmetic. Bubbles at the arch lips are the visible tip of whatever is happening behind the trim.

The front frames and the bonnet

The engine frames can corrode at their lower points and where they meet the bulkhead, and they can also be bent by a past impact. Distortion shows as uneven bonnet and door gaps, a bonnet that will not sit right at the hinge line, or a car that tracks oddly. Frame replacement is a known and well-supported job, which makes it expensive rather than fatal, but it has to be found before purchase rather than after.

The bonnet is a large one-piece assembly with an inner structure that traps moisture along its seams and around the headlamp area. It rots from the inside out, so the underside tells the truth before the top does. Poor bonnet fit is as often a frame or shell symptom as a bonnet fault, which is why the two are inspected together.

Reading a repair

Honest repair work has a signature. Original factory spot-welds have a regular, machine-made look; drilled-out and rewelded panels look different, which is fine, but the difference tells you a panel has been replaced and invites the question of what else was done at the same time. Repair sections that cover only the visible face of a sill while leaving the structure behind it are the classic cosmetic job, and they buy a few seasons at best.

Documentation settles most of this. A restoration with photographs of the shell stripped, the sections fitted and the dates attached is worth trusting. A car described as restored with nothing to show for it should be priced in your head as unrestored until proven otherwise.

Keeping it from coming back

Prevention is unglamorous and effective. Keep drain holes clear, dry the car before it goes away, treat enclosed sections with a cavity wax on a schedule, and fix water ingress at the seal rather than mopping up after it. A dry, used car stays sound far more readily than a polished one that sits damp. The restoration page covers what to do when prevention has already failed, and the buying guide sets the bodywork check in the context of the whole car.
