No you don't, not necessarily!! You've answered you're own question there though!! If it's a ten yr old car it's coming off then it'll most likely be newer than that!! Whats the big deal anyway? If i want a 2nd hand one, isn't it my business why i want one? If i paid stealer prices for all the parts for all 6 of my cars i'd be very poor, so if it lasts a 3rd of the time for a third of the price i'm happy. Not that i have to explain myself to some internet profet, so why not let people answer the question and sit there and wonder.ok!
