I was given a lease car, Infiniti 4 door sedan around 2005. Drove it for about 2 years. I can’t remember the model G something, 6 cylinder 24 valve. For its time, it had the best technology package of any car. I really enjoyed it.
You probably had a G35.
We just bought a low mileage 2009 G37S convertible last year. My wife loves it.
