Hah, I figure you'd say something like that. Well I could say a lot about it, but if you're truely interested, read below. It's what I recently posted on my car forum:
"So I'm moving out for the first time and going to be going to school in San Diego this coming Fall. Of how much I'm madly in love with my Z, I'm considering selling it for a better daily driver. There are a few reasons for this. One is that I'm going to be driving home and back a few times a year and really don't look foreward to putting that kind of mileage on the car (550 miles each way). Second, we're selling our beater Suburban soon and I won't have a car to use for road trips (I'm considering a grand cherokee) and there's no way I'm strapping a storage shell on the Z
I basically figure that I should maybe sell the Z before I begin putting even more miles on it. I just passed 70,000 on the odometer and feel that someone might be able to put it to better use than me running it up as a daily driver. Man I wish this could be my project car...

"
So I'm basically wondering if I'd be better off letting it go now before I begin to maybe face turbo problems or the such. It's also overdue for an expensive 60k checkup. I've kind of been getting these ideas lately where I don't like driving a sportscar daily. I'd love to have some sporty/luxory car like an M5 or an Audi for daily use, and a 300z or the likes for a sweet project car. Shucks.
