Jaguar E-Type Restoration

Jaguar designed the E-Type in three structural parts, and a restoration follows them. In the middle is the monocoque, the welded steel centre section. Bolted to its front bulkhead is a frame of square Reynolds steel tubes carrying the engine, the front suspension and the bonnet (hood), which is hinged at the frame's front end and comes off whole. Under the floor, the rear suspension, its differential and its inboard brakes sit in a steel cage held on rubber mountings, which drops out as one unit. The front frame is itself built of side-members and a cross-member, and Motor Sport explained the point of that in 1961:

So a restorer can unbolt the frame and the rear cage, lift the engine and gearbox (transmission) out together, as even a new clutch demands, and be left with the shell. A full restoration then runs in stages: record every number and order the car's Heritage Certificate; strip it; replace the front frame's tubes where they have corroded, rather than patch them; repair the shell, keeping it true; then paint, rebuild the mechanical parts, wire it, retrim it and put it back together.⁠source 3​source 4​source 5​source 2

The shell takes the most. Motor Sport's account of an early roadster's restoration in 1989 found "The outer sills were rotten and needed replacing as were the panels that made up the centre-section under the car"; the boxes of the sills (rocker panels) and centre section rust from within, the floors go, especially on open cars, and so do the rear arches, the mountings of the rear cage, the boot (trunk) floor, the door bottoms and the scuttle. A coupé adds the seam between its outer and inner rear wings (fenders) and the tailgate. Replacement panels exist, though on the very earliest cars they may need altering: the 1989 restorer's had to be modified, because, it appeared, his car was "a little shorter than later Jaguars". The work needs equipment that keeps the shell true, one restorer's guide warns, and "most body shops likely won't have the skills".

The mechanical work is more straightforward. The XK six is durable if it has been maintained, and rebuilding it is a specialist's job. The rear cage, once out, gives access to its bushes, radius arms, bearings, drive shafts and the inboard discs. Wire wheels can be rebuilt and re-chromed, as the 1989 roadster's were, and every piece of trim is made new; that restorer re-polished the patterned aluminium of the early car's tunnel, console and centre panel. Jaguar's own parts service, Goodwood's guide notes, supplies E-Type parts "up to and including replacement engine blocks".

Prestige & Performance Car gave these as typical costs in Britain in 2026, its figures for that year:

No source read puts a figure on structural work. Whatever it costs, Goodwood's guide asks for documented evidence of any restoration work.⁠source 1​source 5​source 2​source 6

A restorer aiming at the original car has good references. The Jaguar Heritage Trust's Heritage Certificate gives the car's original colour and trim, its dates and its first destination from the factory's records, and the Trust's paint-code service gives the original paint's name and code, with the codes other paint makers use; in October 2026 the paint code cost £50 plus VAT and postage. Jaguar's colour lists are on the colours page. The certificate records the car as built and, the Trust says, does not confirm its identity, originality or condition today.

For the finest detail, the Jaguar Clubs of North America's judges' guide to the Series 1 sets out what their concours judges look for, from the car-number plate and the four styles of dashboard to the flat and recessed floors and the inside and outside bonnet latches, and it reproduces Jaguar's own change points from the factory's bulletins. Its appendix on fasteners shows how far the detail goes: the factory used bolts by several makers, Bees, Rubery Owen and GKN among them, with black heads on early cars and plated ones later. The guide also treats a Heritage Certificate as overriding Jaguar's colour charts, and it cites Anders Clausager's Factory Original Jaguar E-Type for some of its dates.⁠source 7​source 8​source 9​source 10​source 2

Many restorations improve the car as well as renew it, and the buyers guide lists the usual changes. Motor Sport's 1989 roadster was given a pair of Kenlowe fans, "as the earlier cars were prone to overheating", and an engine balanced, lightened and polished, with D-type camshafts and bigger inlet valves, which gave about 35 bhp more than standard on a rolling road. The article also says the car was given "a servo, a feature only introduced on the 4.2"; in fact the 3.8 had a Dunlop bellows servo from 1961, and the 4.2 brought a new type.

Original and improved cars are both legitimate. What matters is the record: a restorer should note every change and keep the parts that came off. Cars taken further, with modern engines, gearboxes and suspension, are on the restomods page; Jaguar Classic's own restorations, its Reborn cars, are on the Reborn page.⁠source 1​source 3​source 11​source 2​source 12​source 13

The clubs help their members with the work. The Jaguar Enthusiasts' Club offers technical advice and pre-purchase inspections, and the Jaguar E-type Club keeps a technical library and arranges specialist discounts, which it says "helps those members restoring, maintaining or upgrading their cars". The parts page has the clubs and the parts suppliers.⁠source 14​source 15
