What is the value of Classe P401 ?

Hi,I am every week reader but first time posting here. My Classe P401 (400W/Ch at 8ohm, 800W/ch at 4 Ohm), a predecessor of CA-401, developed some noise on both channels so I shipped it to factory for checkup and possible repair. It was otherwise working just fine. Without naming the packing and delivery company here, I want to say it was both externally and internally damaged when it arrived at repair facility. It wont even turn on, heatsinks were bent, handles we bent, the transformer cover was broken inside, so it did look like it took a serious hit. The repair cost estimated by the company is over 5000 dollars, I think because now they have to check everywhere as the unit does not even turn on. I had declared the value of the amp at 5000 dollars, I thought was a fair upper limit for value for a 400W/ch high end amplifier given it is over 25 years old. I have filed a claim with the packing/delivery company but it keeps getting rejected because they cannot establish its value. The only place they can establish a value is from some used goods website which tells them that the value is 3 dollars (quite a joke but people who have to pay a claim would love it :-)). The only other place I can find the value of this amp is with a Chinese seller who lists it at close to 4000 US dollars, but the company will not accept a foreign value, which honestly is a lame excuse because we trade with China for everything and the conversion value is well established by Federal Reserve (I sent them the conversion and also the phone number of the vendor in China). So I am wondering if anyone here has the same amp and what would you all think is the fair value of this amp ? Thanks in advance
