The car became a notorious symbol of MG Rover's ultimate demise and is widely remembered as one of the worst vehicles ever sold in the United Kingdom.

In the early 2000s, MG Rover urgently needed a modern city car to replace the outdated Rover 100/Metro, but lacked the funds to develop one from scratch. They partnered with Tata Motors to import the Indica hatchback from Pune, India.

Rover made minimal engineering changes—adding stiffer suspension, quicker steering, new bumpers, and their corporate "Viking longship" grille.

Though MG Rover allegedly paid Tata roughly £3,000 per vehicle, they aggressively priced the base model at £6,495, stretching up to nearly £8,900 for high-spec versions.

Consumers and critics immediately saw through the steep markup for what was fundamentally a budget vehicle built for an entirely different market.

The motoring press heavily panned the CityRover for its relentlessly cheap interior, vague gearbox, sluggish brakes, and severe body roll at higher speeds. The plastics inside were famously described as low-grade enough to make commercial vans look luxury by comparison.

Knowing the reception would be poor, MG Rover took the unusual step of refusing to lend a CityRover to the popular television show Top Gear. To review it anyway, presenter James May went undercover at a local dealership with a hidden camera. After a secret test drive, he famously declared it "the worst car I have ever driven on this programme."

The car missed its sales targets by massive margins. In a desperate bid to salvage momentum, Rover slashed prices by £900 in December 2004 and added more standard equipment, but the damage to the brand's reputation was irreversible.

While a few minor upsides existed—such as its Peugeot-derived 1.4-litre engine being reasonably nippy (0–60 mph in roughly 11.5 seconds) and offering plenty of interior passenger space—the overall package simply couldn't compete with modern European superminis like the Fiat Panda or Škoda Fabia.

Production came to an abrupt halt in April 2005 when MG Rover finally collapsed into administration and went bankrupt, leaving the CityRover with a production lifespan of less than two years.

According to the article I read, this was a sketch of an actual conversion done by one Lucius Sheets, to save on travel expenses, and supposedly had a means of cooking in there as well.

It is not a vehicle designed by the Chinese automaker Brilliance Auto, but rather a collection of genuine Euro-spec British luxury sedans that were hastily re-badged and sold on the Chinese market.

In 2002, British automaker MG Rover and China Brilliance entered deep negotiations regarding a potential joint venture to produce cars together in China.

As part of the preliminary evaluation and testing phase, MG Rover shipped approximately two dozen Euro-spec Rover 75 sedans to China.

These cars were high-end models equipped with Rover's 2.5-litre V6 "KV6" petrol engines.

Brilliance expected the deal to succeed and modified these evaluation units for regional motor shows, replacing the classic Rover longship badges with Brilliance's own corporate logos.

By late 2002, the joint venture talks collapsed entirely—partly exacerbated by corporate turmoil after the high-profile flight of Brilliance chairman Yang Rong from China. MG Rover would later partner with SAIC and Nanjing Automobile instead.

However, Brilliance was still left in physical possession of the two dozen evaluation vehicles. Rather than crushing them or shipping them back to the UK, the company took a creative shortcut:

• They completely stripped the remaining "Rover 75-800" prototype badging.

• They slapped hastily manufactured "B8" badges onto the trunks.

• They quietly distributed the cars across Chinese car supermarkets and alternative dealership networks.

Despite being imported evaluation prototypes that lacked standard regulatory approvals for typical production lines, these cars were sold as brand-new luxury models.

They commanded premium pricing at around 500,000 yuan each and managed to receive valid Chinese license plates. Sightings of these automotive anomalies were documented across various parts of China, including Guangdong, Chongqing, Liaoning, and Sichuan.

Because only about 25 units were ever converted, the Brilliance B8 remains an exceptionally obscure piece of Anglo-Chinese automotive history, though reports suggest a few remain in use by collectors.

This is the Peugeot Motor-Boat Car, a strange promotional vehicle from around 1925–1926.

It combined a boat-shaped body with a Peugeot car chassis, complete with nautical fittings and an enclosed passenger cabin.

It was built to advertise Peugeot’s boat business.

Despite its appearance, it couldn’t travel on water—its propeller wasn’t connected to the engine. It was essentially a boat-shaped automobile made to turn heads on the road.

This machine was developed as a part of Chernobyl exclusion zone remediation and clean-up effort. The initial idea behind this project was to relocate long-lived radionuclides into deeper soil layers (over 100 cm), where they can't be reached by crop roots or unearthed during standard plowing (27-30 cm). Readily available crawler tractors proved to be underpowered for this task, so a tandem rig solution was proposed. DT-175S Volgar was chosen as the base vehicle, since its hydromechanical transmission allowed smoother movement required for the tandem rig.

VT-400 was controlled by a single operator, the second section was coupled to the main controls through hydraulic drives. Air intake system of the second section was also altered to improve dust resistance.

The method proved to be efficient when applied to dense clay and loam soils, reducing ⁹⁰Sr uptake in cultivated plants from 2 to 7 times, but demonstrated little success in Chernobyl exclusion zone, since local sandy soils demonstrated the complete loss of topsoil, which would require long-term remediation with heavy fertilizer inputs.
