I have a cat C V6. Check that you can get it insured, as you may find your insurers won't cover it. They won't check if the car is damaged repaired unless and until you make a claim, and they won't ask when you take out the policy. You have to do the digging.
At the lower end, where a lot of these are, you won't find a lot of movement on price, and they'll still need the usual issues sorted.
As a cat C owner, I would agree that it's worth shopping around and trying to find an undamaged one.
Best of luck.
