is it a bad idea to buy used springs? they are the h&r sports. he said they got about 5k on em. they were on ebay for like 100 shipped but the auction ended with no bidders. we have been in contact since and im gonna see if he will do 75. its some store but a customer left them and bought some coilovers for the adjustment factor. no box no warrenty by the way. is there any reason why buying used springs is a bad idea? thanks everybody
