Mine does everything I ever want of it. Right now it is my on again, off again daily driver. The other car is an older, big cushy Mercedes so thats it's competition. And guess what, I'd rather be driving the rover every time.
I'll give the truck some attention like checking the fluids about once every 3 months (more often if I break something wheeling it) and probably do a proper service (change oil/filter, check points and valves etc...) about once every 6 months. If I drove it more, then it might need a little more servicing but not much.
One of the best things about a series truck is not just driving it but actually owning it. They do require more maintenance than a new car but none of it is beyond the ability of your average person willing to learn. The great thing about them is that you actually can work on them. It's quite empowering once you figure it out.
Do be honest with yourself though. If you can't deal with lifting the hood for maintenance or using your muscles to stop and turn, then this might not be for you. Also, if you are one of those people that finds themselves racing around everywhere, then these trucks won't satisfy.
The only down side (that I see ) to driving and owning a series truck is that your fingernails may never be clean again.
