Hope this is not to far off track
in Australia we used to have what i think is similar to trans-am racing.
it was a mix of home grown and imported cars (now its just home grown v8 racing)
the biggest race each year (still going) is mount panorama at bathurst
it is a 1000 klm enduro.this is a public road shut of for racing once a year.
last year they ran the touring car masters there before the big race.
here is a bit of footage (there is more on you tube if anyone is interested)
you mite spot a few cars you recognize
