Easy Lcd Monitor install??

hey im in the market for tv's to put in my car. and i was wondering which tv's would be the easirt to install and require the least amount of abilty to install it. i was thinking the head rest tv's but i would prefer some thing up front. also do these tv's plug into the cigerate light er or do u have to run wire and finally how would i hook ps2 up to any of these tv's http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=48608&item=3091817058

a monitor (TV) for the car will have inputs for a PS2 or other such device, just like the home version.
