Prior to 2006 there was no grand touring version of the Z. The 2005 & earlier touring trim didn't have the Brembos (they were only available on the track model, not even the "performance" trim had Brembos
I'm not sure why everyone says that. I really don't. I've been to a couple of Z forums so far & I find threads like this with people claiming they never made a 2005 Grand Touring version.
I have a copy of a Nissan article where Nissan said they were going to offer a Grand Touring model in 2005 mid year & that's what they did.
From the information I've been able to gather the 2005 Grand Touring was only available in a Roadster model with a 6 speed transmission & it DID come STANDARD with BREMBO brakes, LEATHER seats, BOSE stereo with 7 speakers & 6 CD changer. Maybe they made a hardtop who knows?
Why am I so sure of myself? Simple: My neighbor bought one brand new in 2005 & I purchased it from him in November 2014. It's mint with 22K on it & it's sitting in my garage right now. That's all the proof I need.
It came standard with brembo brakes, leather seats, Bose stereo with 7 speakers, 6 CD changer & 18" wheels. It was the most expensive model available in 2005 even more expensive then the 35th anniversary model. The MSRP for a 2005 Grand Touring Roadster with no additional options on it was $39,200.00.
Mine also has a few extra options on it like the navigation system a $2000.00 option. The Ultra Yellow paint was an extra $500. The total window sticker price was $42,700.00. My 2005 Grand Touring Roadster was manufactured "mid year" exactly when Nissan said they would start producing them. It was manufactured in January 2005 & my neighbor purchased it off the showroom floor in March of 2005.
Yes, 2005 Grand Touring Roadsters exist!
