Besides cost which these are very costly vehicles, I think there are other things to consider to make your decision. What are your needed drive ranges and what are the availability of fast charging options in those areas. For me the going to the airport, Orlando or my brothers means unless you have over 400 miles range your going to need to add 4 hours to your round trip time. That would make me not go most of the time which I don't want my car to dictate how I live. I have good structure at. my house to support a high level charger,but given my needs a plug in hybrid meets my requirements better. Issue is for example the LX NX is not ideal, but it is the best plug in for luxury and range. The issue is even with a tax credit its is hard to justify the $14,000 up charge for this over the gas version or $11,000 over the standard hybrid. There is also that Lexus only brings about one fifty of these into Florida so even large dealer only get one.
