I bought both my parents new old machines now that they retired, and I opted for a T480 for both. They’ve been called The Last Great ThinkPad over on r/thinkpad since they are both powerful - first generation with a quad-core processor - and nicely upgradable. The upgradeability also means that you don’t have to worry overly about the amount of RAM a used model has: you can always add more cheaply (and very easily).
