Some cars simply check the boxes. Others become the benchmark. This 1955 Jaguar XK140 Roadster is the latter.
Restored over the course of more than a decade between 1978 and 1989, this XK140 SE presents exactly how enthusiasts hope to find one, finished in timeless red over tan leather, powered by the legendary 3.4-liter inline-six with dual SU carburetors, and paired to the proper 4-speed manual transmission. Every detail feels right, from the split windshield and Lucas fog lights to the 16” wire wheels and full-width chrome bumpers.
Inside, the adjustable tan leather seats, Smiths instrumentation, and classic Jaguar driving position deliver the kind of analog experience that simply doesn’t exist anymore. This is the era that built Jaguar’s reputation.
What makes this example stand apart is the depth behind it. Accompanied by a Jaguar Heritage Trust Certificate, Vehicle Information Record, JCNA judging sheets, historical photos, service manuals, parts catalogues, and even the tool roll, this is the kind of documentation and provenance collectors search years for.
If you’ve been waiting for the right XK140, this is the one worth paying attention to.

Race car on the street? We say yes! This one came all the way from Japan. Our client brought it to us for service to make it more street friendly. We did an engine out reseal, installed tins to help with cooling, got heat back in it, added a new shifter, and some other odd and ends.
It’s just cool inside and out.
The car sold on Bring a Trailer — now what?
Just like the prep work before the auction, our detailed process continues after every car sells. We complete a full post-sale checklist, handle the paperwork, and assist with transport coordination before the car heads to its new owner.

The Porsche 959 rewrote the rules. All-wheel drive, adjustable suspension, lightweight materials, twin-turbos, and sophisticated electronics.
This one is in for some service to investigate and solve an oil leak.
