English about convertible

To be honest, the LZ score of this question is a bit low. . Give some extra points. .

And not only these five statements, but also Cabriolet. Let me talk about the meaning of these six words found on Baidu:

Convertible-a car with a removable folding hood

Convertible-(formerly) a covered car

Open-top passenger car or light carriage

Convertible and convertible should be four-seater convertible, roadster is two-seater, which should be correct (because there is almost no relevant information on the internet, so I can only infer it myself).

Volante-briskly.

Spyder-(can't find the word ...)

Spider-(Although it can be found, it has nothing to do with cars. )

Personally, I think the models of spyder and spider don't look much different. It should all be used for two-door and two-seat sports cars. As far as I know, spyder is only used by Lamborghini, Maserati and Spyker, while spider is only used by Ferrari and Alfa Romeo. Plus spyder can't find English meaning, it should not be English, but it is estimated to be Italian. As for why these two words are so similar, I guess it's just a choice between brands. The former follows the original word, namely spyder, and the latter changes spyder into a very similar English word-Spider, thus giving the word "spider" an additional meaning of "convertibility" ... (These are all my wild guesses ...)

The Volante is only used by Aston Martin, and Martin's V8 Vantage uses Roadster, so the Roadster for a two-seater sports car is more certain.
