The memory recycles itself on most of them, depending on the size of the Storage Card you use some can have hours of footage recorded. Most times they record in chunks of a few minutes at a time and then cut into the next segment (you wont generally notice the change into the next segment during playback.) Once the card is full most models start from scratch and record over whats already been recorded. So if you have some footage you want to take off take it off asap.

Micks garage has the best looking one ive seen in a long time for the money and is very discrete. i think its about 99 Euro.

Personally id have someone with knowledge wire it up for power behind the a frames to the fuse board or other power source as plugging in and out the 12V cigarette lighter will get very tiresome and he will end up just not bothering and never using it.
