Allow me to put to use my years of gear geeking...
If you're "car camping" then almost any old tent will do. You want a "freestanding" tent because having to put in stakes is a pain in your butt.
I highly recommend getting a 2 man and not inviting anyone to share. When I car camp I sleep in a 2 man with an inflatable coleman bed (almost as comfy as my mattress at home).
Remember:
Freestanding
2 man
3 season (you do NOT need a 4 season).
look for good ventilation and a decent rain fly.
Don't spend more than $150.
Here's a good sample

If you're ever going to go backpacking, everything changes. That's when the weight weenie in me can give you lots and lots of options.
