Like Ras said we have our reasons!!
In your post you have some valid points, but let me tell you from someone who has a r34 gtr, that doesnt require fixing, for me and alot of other people that own them the are not an easy car to live with day to day. For starters they are Fu#king hard to get in and out of in tight car spaces, and before you say it no im not 50 im 28! Mine like others with coilovers are pretty low, especially with the nismo bottom lip, you would be amazed at how hard some curbs are to get up! They have a fair degree of road noise, they fit absolutely F#ck all in the boot, I have never seen one with a towbar, etc etc.... there are many reasons for many people why these cars arent great daily drivers...
Having said all that i love that i dont drive my gtr everyday, because on the days i do drive it, im not running late for work, i dont have to be anywhere, i can just enjoy the car for all its brilliance...
