My expert take on this offerThe last of anything tends to carry weight. The last of a beloved production run carries considerably more. Chassis 1E18367 rolled out of the Browns Lane factory on July 29, 1968, and according to the Jaguar Heritage Trust Production Record Trace certificate included with this sale, it is the final left-hand-drive Series 1 roadster ever dispatched. That's not a seller's claim scrawled on a Post-it note. That's factory documentation, and it changes the conversation entirely.1968_jaguar_xke-series-15-roadster_xke002-85876 The ownership story is unusually tight for a 57-year-old British sports car. The original owner held it until 1984. A friend of the eventual seller then kept it for the next three decades before it changed hands in 2014. That's two careful custodians over 46 years, which in E-Type terms is practically a provenance miracle. The current owner then sent it to Sport & Specialty of Durand, Illinois, where it spent from 2021 to 2024 being comprehensively rebuilt: acid dipped, straightened, fitted with replacement floors and rocker panels, repainted, re-trimmed, mechanically sorted, and upgraded. Total documented cost: over $318,000.The result is a car that started life in Willow Green and emerges in Opalescent Maroon over Saddle leather, a combination that is richer and arguably more commanding than the original spec. The color change will bother purists, and they are not wrong to note it. But the original four-speed transmission comes with the car, the body has been properly sorted rather than simply sprayed over, and the refurbishment records are photographed and viewable in the gallery. This is not a flip. It is a decade-long project from someone who clearly intended to keep it.Video walk-around on this exact 1968 Jaguar XKE Series 1.5 for saleNeed New Tires?

It is collector shorthand for the transitional cars built during the 1967-68 changeover from Series 1 to Series 2 production. These cars wear exposed headlights and revised front-end detailing while retaining the small grille opening, corner-mounted turn signals, and above-bumper taillights of the earlier car. Roughly 2,800 open two-seater roadsters were built in this configuration. Chassis 1E18367, as the last left-hand-drive example in that run, occupies a specific and documentable place in that number.1968_jaguar_xke-series-15-roadster_xke007-85888 Mechanically, the 4.2-liter twin-cam inline-six has been fully rebuilt and breathes through retrofitted triple SU carburetors with an electronic ignition and an electric fuel pump, a quiet quality-of-life improvement that experienced E-Type owners will appreciate. The Tremec five-speed manual transmission replaces the original four-speed all-synchromesh box, the driveshaft and rear axles have been rebuilt, and a stainless-steel exhaust system runs the length of the car. The suspension has been refurbished with GAZ coil-over shocks at all four corners, an upgrade that meaningfully improves body control without destroying ride quality. The four-wheel disc brakes have been refreshed. Chrome-plated 16-inch Dayton wire wheels carry 205/60 Michelin Defender tires on two-eared knock-offs.The five-digit odometer reads 65,000 miles, with approximately 150 of those added under current ownership. Given the scope of the refurbishment, the effective mechanical mileage on this car is closer to zero.What is a fair top-end bid for this car?Classic.com places the average auction result for the E-Type Series 1.5 at $72,922 across all body styles and conditions. The high watermark is $162,000 for an exceptional 1968 roadster sold in March 2025. A standard driver-quality Series 1.5 roadster with similar modifications and documented mileage trades in the $65,000 to $85,000 range.This car is not a standard example. The Jaguar Heritage Trust documentation of its position as the last LHD Series 1 roadster built is a genuine collector credential, the kind that does not appear often and does not trade at average prices when it does. The $318,000 in refurbishment records will not translate dollar-for-dollar into hammer price; the market never pays full ticket on restorations, regardless of how thorough. But the documentation, the provenance, the no-reserve format, and the quality of the work completed suggest a realistic ceiling somewhere in the $110,000 to $135,000 range for the right buyer.1968_jaguar_xke-series-15-roadster_xke012-85900 The color departure from original Willow Green is the one variable that will suppress bidding among the most historically minded collectors. For buyers who prioritize driving quality and documented significance over factory correctness, it is a non-issue. The original four-speed gearbox is included, which at least leaves the door open for future restoration to original spec if the next owner so chooses.At $70,007 with six days remaining, this auction is significantly behind where it should finish.1968 Jaguar XKE Series 1.5 quick takeThere are E-Types, and then there are E-Types with a story. Chassis 1E18367 has both a documented story, the last LHD Series 1 roadster built, and three years of serious, invoiced specialist work behind it. The Tremec five-speed makes it a car you will drive. The GAZ suspension makes it a car that will reward you for driving it. Opalescent Maroon over Saddle leather makes it a car people will stop and photograph. Get a PPI from a Jaguar specialist, verify the Heritage Trust documentation independently, and if it comes back clean, the buyer at the winning bid is securing a piece of numerically documented E-Type history at what is shaping up to be a significant discount to replacement cost.
