l prefer a 350z coupe, if that helps

Yes. Many people at my school have sutomatic 350z is instead of manuals. Most 350z is are Automatics probably.
You can buy any car with manual or automatic.

Only the real performance cars do not offer automatic like Ferrari, Lamborghini, and some Porsche models.

u can get either a

5-Speed Automatic or a 6-Speed Manual

the automatic is an option & cost more.

did u know?

Automatic Transmission Service:
You will find that u cannot loosen the transmission fluid level dipstick or locate the dipstick handle (there is not one). That is because the new dipstick is bolted in place & should be serviced only at the dealership. Attempting to change or service the fluid on ur own could potentially damage the transmission.
Automatic Transmission Fluid:
Another reason to have ur transmission serviced at the dealership is the special automatic transmission fluid that is required (Nissan Matic-J A/T fluid). Using other Nissan or commercially available fluids may cause damage to the transmission that will not be covered by the limited warranty.

Low Ground Clearance:
First-time sport car owners may not be aware the sports cars have low ground clearance. Therefore, special care should be taken when driving over speed bumps, dips in the road, or driveways.
Fuel Requirement:
Premium unleaded fuel is required for optimum power performance.

l had an auto 2003 350z and then bought a stick 05 350z last year.

Having both, l can tell you that you will have so much more fun with a stick. l had never driven stick before this car, so l sucked, but learned and got better.and l am so glad l bought a stick.

l commute in traffic to work (chicago), which sucks, but still worth it over getting an automatic again.

yes, the Enthusiast trim comes in automatic.

And you're getting the 350 confused with the G35. The 350 only comes as a 2 door coupe or convertible. The infinity G35 comes in a 2 door coupe or 4 door sedan
