Well yeah I guess if you're buying a used machine from six years ago with millions in existence because tons of businesses bought them it'll be cheap no matter what manufacturer it's from. Thinkpads do hold up better against age than most.
you can routinely find i5 variants here in the US for that price. Im sure the i7 models are more expensive, those are sought after, but frankly as long as the i5 models have 4 cores, they're fine. Last i checked a t480 running a quad core i5 is 75% of my r5 2600, which is more than enough for mild productivity work.
A last generation ThinkPad is still going to be a beast you can get 6-7 years out of. I have a gen2 X1 that was still a beast until the offspring spilled a Coke on it.
