I bought my Z in February 2012 as well.
I picked up a Honda Fit for a daily last Fall. Keeps the miles off the Z, the Z doesn't have to sit in a parking lot all day baking, the deterioration of the roads in the winter no longer chew up the front of the Z. Now the Fit is subjected to all this abuse, but I do not care as it is a beater after all.
So look at getting you whatever economical beater of your choice and carry on.
