I bought that specific model because they're a step up from the E-series (which is actually good now), but not as expensive as the X or T series. I'm very familiar with Thinkpads (I personally have owned 5, and have bought 3 for family, all used, all functioning perfectly). That specific model does not have soldered ram, has lots of replacement parts, is still fairly new, I'd owned an L14 Gen 1, and to be honest, it was just a good deal considering it was in mint condition.

With thinkpads, assuming you're buying used, you can pay the premium for a T or X series, and get a laptop with essentially the same parts, but maybe a better screen or chassis, or you can save money and go with the L or E series. NB, the T and X series oftentimes have soldered RAM, so if you're not satisfied with the amount of ram already in it, do your due diligence to ensure that the model support using SODIMM/replacing the ram.
