Loss of value of new boxsters against used 911

hello, I am just thinking…. maybe you can help me and estimate in about which car the lower value loss (as a rule / estimated / assumed….) are available “will”. accept: brand new boxster for approx.45-50000,- € against used 911 (996) bj. approx.2002 and medium km-performance also for approx.45-50000,- € according to what I have seen with mobile etc., the value loss of the boxster should be around the 10% or 4500,- € in the first years. (estimate i What do you think, the used 911er has a greater loss of value or a lower one. Hold 2-3 years if this should be decisive. what do you think? p.s. please really only discuss this question here. not if one or the other is the better car etc.. also not as far as the other costs are concerned etc. please really only what you “estimate” about the future loss of value thank you!
