I have had a Corsa and Astra and didn't really get on with either.

Obviously I have never gone over 70mph in my ST, but I have heard what others have done On the flat she pulls up to 120mph fast, then takes a little longer to get to 130mph where she stops.
When tried downhill she went up to 140mph on the speedo and that was not far from the rev limiter and she wasn't going any faster.

Has anyone had a dabble with the new golf 2.0 tdi sports? They are bloody fast, it was neck and neck. Off the mark I kill them but when you are going on the motorway its not as easy.
