Looking for insight from Z owners who also own a GT-R

[Divexxtreme]

Hi guys,

I've been considering getting a 'relatively' lightweight, RWD, 6-speed car to compliment my GT-R.

I'm pretty much all over the map with this; as I'm thinking about used Z06s, E92 M3s, 370Zs, '11 Mustang GT or Boss 302, 996 or 997 GT3, Cayman S, or Viper.

What I like about the Z is that every time I pass one...I catch myself turning my head to stare at it. I think it's very attractive car, especially with a nice set of wheels on it. I haven't test driven one yet, but I 'imagine' it's quite balanced, fairly quick, and gives good feedback to the driver. The cost of entry is quite nice as well.

Are there any Z owners on here who also own a GT-R? If so, how do you feel it compliments the GT-R? Are they a good garage combination?

Also, I have extensive experience with 911's, M3s, and Z06's...but have never driven a Viper or '11 Mustang. Keeping the price-points in mind, how do you guys who have experience with any of these other cars rate the Z overall?

For example, being as neutral as possible (ya, right), do any of you with personal experience believe a used '08 M3 worth the extra $20k over a Z? That's the type of information I'm looking for.

I do realize that this is a Z forum, and that my questions are covering a lot of ground...but I wanted to get opinions from those that live with a Z everyday.

Thanks in advance, everyone.
