FactBayliss-Thomas existed only because a Belgian firm already owned the name Excelsior.
The Bayliss-Thomas 8.9 Junior (also called the 9/19 from 1924) was one of the range of 4-wheel cars the British motorcycle maker Excelsior began building in 1920 under the "Bayliss-Thomas" name — chosen because a Belgian car was already called Excelsior. An open four-seater sports model, it had a 1,075 cc four-cylinder side-valve engine, a 99 in (2,515 mm) wheelbase and a 3-speed gearbox.

Owning one
We don’t estimate running costs for a car like this. What it costs depends on its condition, its specialist and how it is driven, and an average would mislead.

In 1974 Alfa built a one-off on this Spider: a Porsche-style solid rear window and lift-out roof panels, fewer than 2,000 made, the only Spider ever with a part-solid roof.

Over 100,000 people voted to name this car "Duetto" — but a chocolate-snack maker had already trademarked the word, and a Milan court ruling forced Alfa to sell it as the Spider 1600 instead.

After nearly 25 years of manual-only Spiders, the final Series 4 cars quietly added something Alfa purists never expected: an optional automatic transmission.

The mid-80s Spider's Quadrifoglio Verde trim went all-in on a single look: blood-red carpets and grey leather with red stitching, and it only ever came in three exterior colors.

This Spider was built not by Alfa but by Pininfarina itself, on a platform shared with General Motors.

The 916 Spider's strongest naturally aspirated engine, the 192 PS 3.0 12V Busso V6, was never offered in its GTV coupe twin.
The Frogeye had no boot lid at all — owners reached the spare wheel by tilting the seats forward into the dark cavity behind, a ritual they likened to potholing.

The Fairlady 2000's SR311 update came with a five-speed manual gearbox in 1967 — a genuinely unusual spec for any production car of that era.
