JMFC - being that you are a recent newbie to this forum, the search feature will become very useful to you! You just have to use it... Here is a previous thread on the very same car where 100's of members already viewed and commented on it. Of course, its the thought that counts, but I am really hopeful you learn to use it.

I am not trying to discourage you from being a contributing member, but duplicate threads are exactly just that - unnecessary. Please try to look up things before posting - its a rather simple step.
