The new 3.5-litre coupe, which will be delivered to the first UK customers in the next few weeks, is expected to retain 52% of its original value after three years/30,000 miles, against 51% for the Audi TT 3.2 V6 DSG.
However, the Nissan is priced at £24,000 on-the-road against £29,155 for the Audi, giving it a further advantage in the depreciation battle.
Nissan is also offering the RAC Trackstar vehicle monitoring system as an option on the 350Z, priced at £599 plus an annual or lifetime commitment, which works with the car's immobiliser.
If an attempt is made to start the car, or if the car is moved, pushed or lifted on to a trailer or transporter without authorisation the Trackstar unit will alert a control centre.
The owner is then contacted while the car's location is pinpointed using GPS every 20 seconds and the police are alerted. The system continues to work even if the battery is disconnected.
