I agree with the others. My Passport 8500 does a great job.
Besides the price...it sure does look a whole lot better! May not mean much to alot of ppl but it did to me. I think I would be much happier if the V1 was given a facelift.
Another deciding factor I found, after doing a bit of research, was that Escort actually makes all the radar equiptment that the police use.
And you can send it in for upgrades if needed, although I believe you can do that with the V1 as well.
