Dear RichardR;
I am on my second Viper, and can tell you that both took about six months. If you are a previous Viper owner, it seems to help. Once the Viper hits "D-1", it seems to go pretty fast. You may have a month or so to wait. I am only speaking from my experience.
The new Viper 01' is much improved (in my opinion) over my 98'. You will really enjoy it. Follow the break-in procedure, and change your oil as everyone recommends before 300 miles. I think folks are saying to change oil around 250, which seems extreme. I paid a pile of money as you probably will, so I will follow suggestions.
You will really love this car. Respect it until you break it in and get to know it. The Viper will be here soon!
Sincerely,
Jim
