I plan to buy a 300h as soon as it is available in the Boston area. I am 62 and have had an infiniti for the past 9 yrs. this would be my first Lexus. The NX appeals to me as a luxury cross over that is good for road trips my wife and I plan to take after I retire next year. Plan to pay cash, keep it for 10 yrs and benefit from the fuel efficiency. I too am an engineer and have spent 40 yrs with a high tech company so NX does have geek appeal
