Which one would you like answered first? Any chance of grammar (like a question mark, to signify a question, and some commas to let people breathe)?
The Vauxhall VX220 is slower on-track than the Opel Speedster .
The R34 M-spec is worth so much because it isn't in the game. There is also an MX-5/Miata/Eunos Roadster in there worth 10,000,000cr. I cannot answer the Stratos question, as I have the PAL European version and cannot get the Stratos.
