My MGB always provides a ready and willing subject.
As a side note, you'll find some debate, or at least I've encountered it, about an idea focal length with which to photograph cars.
Even though I'm a wide angle junkie, that's one of the situations where I find a moderate tele(something in the 85-135mm range, full frame) to be useful. That means standing a ways back from the car, so depends on you having enough space. The benefits, though, are just like any other long focal length where you tend to "flatten" the car and isolate it from the background better. Of course if you want to show where it is, that may be counter-productive.
I find that using a wide angle, a small car like the MG just kind of disappears when I'm trying to include the background.
Also, this is a preference, but I tend to photograph low so that I'm at eye level with the grille and not looking down at it.
The banks of a river are, for some weird reason, an oddly appealing backdrop for me. Now that I've moved states, I have my pick of a couple of big rivers and not JUST the Ohio, but I find the Illinois or Missouri much more attractive and tranquil than the big and dirty Mississippi.
This one from a few weeks ago in front of a small marina off Illinois, not far from the mouth. This is a weirdly tranquil spot, and my wife and I got married in the lodge of the state park across the road from here, overlooking this very area.
