Your english is fine.
And you're not alone regarding the Vision GT Cars. A lot of people (me included) would prefer to see more real road/race cars than those fictional ones. On the other hand, the whole project is more than a PD creative epyphany, since it involves the actual manufacturers, designers and engineers. That alone, in the end, is a good sign that the relationship between the gaming industry in general, and PD in particular, is getting closer to the people who make the cars we love and drive.
As for the line ups we have in GTS, sure, more recent cars would be awesome but what we have is not a bad start imo. I do hope to see the list growing soon though.
