The 2004 350-Z Roadster is the 4th Z car that I have owned. By far, its the most powerful in terms of acceleration. It can go from zero to sixty in a heart beat! Be careful ... it's not for the faint of heart. Though the interior is not flashy, it still works. The sound system is better that any of the previous Z cars built. The 6 disc in dash CD player is superb. For the money I couldn't find a better buy. I am sure that I have just as much fun driving my 350-Z as any BMW, Audi, Porsche owner and I have more cash left over. Fun doesn't have to cost a fortune.
I love the engine, transmission and sound system.
Make the seats more comfortable. The same with the headrest. Remove all the buttons from the console and place them on the dash.
