I have received a good offer for a used TS75 (about 25% of a new model). According to the owner he bought it in 2005. Are there any significant differences between a Festool track that is almost 20 years old and the new versions?
The saws are indeed the same. But I would argue that 25% off is not a good offer for a 15+ years tool.
No matter the mechanical state, such an old tool is ripe for a full checkup, re-grease and a bearings change due to the grease being old in them. Once you do that, you are at full retail price but no warranty ... the all-inclusive warranty being like 20% of the Festool tools value.
25% off is a good offer for a 3-year old tool. I.e. one in 100% order but no longer covered by warranty. Would not pay more than 60-65% of a new price for a 15-year old tool. But that is me. YMMV.
ADD:
If you are not already on the Festool tracks, you may want to skip buying a used T75. It is a heavy tool and is not a good daily-driver.
You are much better off getting a used TS 55 or, better, a TS 55 R instead. They are lighter and are meant as the daily drivers. Much, much better tools to get into the "track world" when coupled with a 1400 mm LR32 Festool rail and the TSO parallel guide system ...
Sure, you can use a TS 75 in place of a TS 55. But you will not like its weight for the casual cuts where its power/cut-depth are not needed. So will inevitably be on the lookout for a lighter saw. Getting such an expensive tool only for it to collect dust is a waste.
The Festool 160-168 blade saws are handy one-hand tools. TS 75 is a two-hand "machine". The heft and power are great for when one needs it. But a burden for those 90+ % of cases when it is not needed.
