Just read all these posts, I am sure we can have a thread dedicated to avoidance techniques, hints and tips and include humorous tales of being caught.
My car is made up of bits and bobs, this and that, nothing specific. Buy bits every now and then using all payment types, spread it around a little, leave little trails not massive foot prints. Avoid the 'how much' question by changing the subject as fast as possible or saying you're not sure as don't keep records then legit out of the room sharpish
Good luck to all!!!!
