Asymmetric planar cubic graphs

At Wikipedia I found that "according to a strengthened version of Frucht's theorem, there are infinitely many asymmetric cubic graphs".

Are there infinitely many asymmetric planar cubic graphs, too?

If so, does it follow that there is an infinite asymmetric planar cubic graph?

If so, how could this graph be characterized?

Background

I am looking for an homogeneous and isotropic (in the large) regular graph that could "mimick" a discretized plane (without distinguished directions as in a grid). So an infinite asymmetric 4-regular graph would be even better (reflecting dimension 2).

Unless I'm mistaken, you can add a sufficiently large "cyclic ladder" to the Frucht graph as in:

I would argue that, in an automorphism, the right-hand side would need to be mapped to itself. Therefore, an automorphism of the above graph would imply an automorphism of the Frucht graph (and therefore must be trivial).

An infinite version could be constructed by appending two infinite ladders instead (actually, I'm pretty sure you could attach one infinite ladder).

Nice construction! But to be honest I was looking for an APCG that paves the plane a bit more "uniformly". Look at the Frucht graph here (en.wikipedia.org/wiki/File:Frucht_graph.dot.svg) and imagine it "uniformly continued" in all directions. –  Hans Stricker Nov 18 '10 at 9:11
By the way: How did you draw this graph? –  Hans Stricker Nov 18 '10 at 14:45

I am not sure if this gets at what you mean for the 4-valent case:

Take the infinite graph 4-valent which arises from tiling the plane with 4-gons (squares). Pick one vertex and remove that vertex and the 4 edges attached to it. (We now have four 3-valent vertices.) Join pairs of these 3-valent vertices with two edges each having slope 1. We now have a 4-valent infinite graph with two new 3-gons and a single 6-gon. We can get an asymmetric infinite graph be carrying out this process in various unsymmetrical locations of the original tiling. By starting with irregularly spaced lines (rectangles rather than squares) the two new added edges will have very different directions.
