Last year my wife bought a 2015 Lexus GX 460 brand new for $53k. She test drove a Model X recently and really enjoyed it but her mental agreement to herself is she would keep the Lexus for at least 3 years. However, with the release of the 60D and the $7500 tax credit (which I believe will expire in Q2 2018) she is considering one now. Here are some other considerations New Model X will be about $70k after tax credit Blue Book value of the Lexus for trade in $44k (9k less than she paid) We can afford it but we don't like making irrational decisions Our thoughts on waiting 12+ months - Increased probability the cost will come down (or at least 70k would get you more car and more technology). The more likely we might be able to find a good value in an inventory or CPO Our thoughts on getting it now - 10x better vehicle Capture the most trade in value for the Lexus ~$1500 in fuel savings per year (meh.) $1k referral credit I know there isn't a "right or wrong" way to go here but I realize many of you here have made the decision wait or go now and I would be interested in your perspective. Thanks!
