I'm looking a 2004 Nissan 350z but it has 114,011 miles on it. Is that okay for a first car?

Check with KBB.com and Edmunds.com for the value of the car. When buying a car, you look at many things, not just the mileage.

this kind of miles should be problem for the engine .. however I would be careful about previous owners, making sure they didn't use it heavily for drifting and such ... will stay with standard .. no mods the overall condition is much more important then mileage

my first truck had 160,000 on it, and it lasted a while. just keep up on maintenance and take care of it. theres a saying any engine can make it to a million miles as long as its owner keeps up

I own a 2005 350Z Enthusiast convertible. But I drive a company vehicle. Mine only has 19,400 miles, but has never shown even a hint of a problem. They are good strong cars, but personally I am always skeptical about vehicles with super high mileage. You're likely safer if you're buying from an individual rather than a dealer. This way, you may know the driving habits.
