Hi, welcome and thank you for visiting us on NSXCB!
A few thoughts against your questions ....
I am searching for the NA1 model , white and targa but as i know it is very difficult to find one so the second choice is white coupe and the third is targa on any colour. The first two are going to be really difficult, however the Targa option is easier without a colour restraint ... have a look on Autotrader
my first questions are
how different in power is the AT comparing with MT MT is circa 274, the AT is lower at circa 250, But, it does have a greater, wider torque figure that is effective lower in the rev range IIRC.
What i have to check on this car to be sure that i made the best possible choice?(engine body etc)..The paint and the leather is the last one i worry about. A solid service history by main dealer or recognised specialist, then check or have checked for chassis and body damage. In addition, I would take time to read the very helpful Health Check thread on this site for info on other things to enquire about when you find your ideal Targa.
What is the cost per year of having such a car? (service, parts etc) Depends on many things such as mileage, use etc. By example, I do 5k miles per annum with an annual service and second oil change and budget £350-£400. Do bear in mind that at specific intervals you will need timing belts, water pump, valve clearances and these can add around £800 each at main delear prices. (Cpmbining them will save you ££)
how easy/hard is to have it as a daily driven? As easy as a Civic was the original marketting spin. In the real world you will take more time to park, but in practible terms you can fit a lot of kit into the NSX.
Hope this helps and good luck
regards, Paul
