Can I mount a roof bike rack on a two door car (camry solara)?

a) most likely. I had a roof rack on a Subaru Justy (tiny tiny car, 2 door hatchback). Go to the websites of the systems and you can run a search to determine whether you can install one on your car. b) Thule or Yakima are best in my opinion. I have a Thule rack. If you go to their website, you can use their fit guide to determine exactly what you need for your car. You will need bars, towers (the bit that the bar goes through to attach to your car) and a fit kit. The bars come in different lengths. Try to get one that will roughly be the same width as your car. It will need to stick out beyond the towers a bit for safety, but not too much because you don't want to make your car too wide and they are often right at head height as you are getting out of the car...ouch. Depending on what kind of roof you have, the website will recommend the type of towers you need (my Subaru needed different ones than my Ford uses). Then there will be a fit kit specific to your car. All together, you are looking at at least $200-250. Once you have the bars fitted to your car, you need to decide what trays to get. You can get pretty much any brand. I have used Thule, Yakima and Rocky Mounts on my Thule bars. I think the Rocky Mount (Lariat) is probably the most secure, and it comes in nifty colors (mine is pink, and I plan to get a blue one), and it is relatively inexpensive (about $75 with the disk brake attachment and lock core, I think). But you have to take the front wheel off your bike...it attaches to the fork, which is also where it locks your bike onto the rack. I had the Yakima King Cobra, which I really liked because it does not touch the frame and you don't have to take the front wheel off, but one broke and another failed to go down all the way once and caused some pretty major roof damage to my car when I went into a parking garage (luckily my bike was not on it!!). It also did not work as well on road wheels, though it worked...it just want not as tight as with mt wheels. It also loosened if you were not careful about how you tightened it. ($130ish) I also have a couple of Thule big mouth. It also does not require removal of the front wheel, but it holds onto the downtube of the bike, so if your bike frame is unusual, it will not work (does not work on my boyfriend's full suspension bike) and an older one I have has scratched one of my bikes pretty badly because the plastic got kind of hard as it got older. ($100ish) Yakima and Thule both make racks similar to the Rocky Mount Lariat and they are probably similar priced. c) LL Bean sells Thule online. So does REI. You might even be able to buy from the Thule or Yakima website. I think REI also sells Yakima. Rackbarn sells a bunch of systems online as well. Many bike and ski shops sell them as well if you wanted to look at them in person.

A) Yes it should be possible B) I'm not shore and C) Wal-mart might have some

Unfortunately, I can't add much more than the previous rather non-committal answer, but, yes, I'm sure you can find a suitable rack. I don't think the 2-door vs. 4-door issue is important at all. Go to a decent bike shop - certainly not a general place like a supermarket - and find out from them. I'm sure the first one you approach will be able to tell you exactly what's available.
