ECD Automotive Design can't seem to get enough of shoving Corvette engines into old-school Land Rovers. The tuner did this with a Series 3 Land Rover Defender known as Project Overload, and then again just weeks ago with a tough-looking Special Edition based on a Defender 110. As with all of its projects, ECD spares no expense and will cater to its clients' every whim - for a price. The company's latest custom one-of-one Defender is known as Project Mr. O.

Based on the much smaller 1988 Defender 90, Mr. O has a Corvette LT1 engine and a particularly lavish interior that perfectly showcases ECD's craftsmanship expertise.

As much as we're fans of the all-new Defender, there's nothing quite as cool as a classic that has been beautifully reinvigorated. Project Mr. O is finished in Night Mission Green with a Rice Grain white hard-top roof. It rides on Goodyear Wrangler DuraTrac tires wrapped around 16-inch Heavy Duty Wolf steel wheels. The fold-down side steps are made of teak wood, and it's details like this one that set apart everything ECD touches.

It's in the interior where Project Mr. O makes the greatest impression, though, with the upscale look juxtaposing the rugged nature of the off-roader. Top-quality stitched leather covers most surfaces and the color combination is a striking Spinneybeck Copenhagen with Off-White stitching. This is contrasted with Fox Moss Green tweed. Seriously, some of the fittings look good enough to impress the team at Bentley's Mulliner division.

The front seats are heated Recaro Cross Sportster CS items and the headrests are custom-embossed with the client's initials - clearly, this owner has good taste. Instead of ordinary door pockets, each door has suede satchel bags. Other gorgeous touches include wood veneer on the center console, Smiths replica gauges, a headliner in The Merchant Fox Moss Green tweed, and an Exmoor Williams steering wheel with white stitching.

At the back, there are two inward-facing benches for extra passengers that come with suede leather cushions. Even the load area is opulent; it comes with dark wenge wood floors with metal rivets.

"Our world-class team tailors every seat, steering wheel and door by hand," said ECD Co-Founder Elliot Humble. "The Spinneybeck Copenhagen leather on Project Mr. O with vintage fluted style stitching pulls the whole build together in a uniquely ECD way."

While ECD has retained an old-school charm befitting a 1980s Defender, there are several modern touches to make Mr. Project O even more comfortable. It comes with an Alpine Radio, Bluetooth, wireless Apple CarPlay, and a Kenwood eXcelon subwoofer.

As mentioned earlier, this Defender is powered by GM's LT1 engine. It's paired with an eight-speed automatic transmission and those Borla stainless steel dual sport exhausts should emit quite a roar. Upgraded heavy-duty axles mean that this posh Land Rover can still tackle the rough stuff with confidence. No price was mentioned but this totally bespoke Defender is unlikely to have come cheap.
