80's kid all my favorite cars growing up had to have a turbo.Don't like any thing with a turbo, but the cars you mentioned should challenge any simracer.
Does it work for you? I discovered it myself. But then it didn't let me actually pay. Just no response to my mouse clicking...That's why I didn't tell it here. Didn't think it works this way.Nothing for me neither, points seem to be going to people who have' touched it for a while - from what I've seen on the steam forums.
Another thing I discovered whilst on their forums is a big discount if you pay in rubels. Example, 5000 points in Gbp = £38.29
If I change the currency to RUB, steam converts it to £23.91 when I go to pay. Not a bad discount!
