I can see why people loose interest a bit when it's been something you've desired later in life (and around the 2000's), but for some of us the supra was our dream car growing up, seeing it on Lexus stands at car shows on launch and promising yourself that you would one day own one.
To me it's all about enjoying it for myself, it's the ultimate selfish possession to someone with a young family, but like has been said earlier sometimes you need a bit of fun in your life.
I'm driving mine less and less due to family life, but it makes the times when I do take it out all the more enjoyable; getting to know it again is like getting a new toy all over again.
I'll never loose the love for them.
