BLS or BSE – which is the more problem-free/long-lived short-range motor?

Good morning, There are many individual information about each of the two engines, but what about a direct comparison in terms of maintenance costs, susceptibility to errors, etc. with the main short-range profile? Which engine is the more durable, low-maintenance short-range motor of the two? The answer is probably obvious, but who knows, maybe I’m completely wrong with my assessment (BSE). Background: We recently had a Caddy Li now I would have the opportunity to get a Caddy Maxi Life 7-seater with BLS engine and DPF (charging coefficient 21.3%, ash mass 17g) from 2010 (unfortunately without a heater) with just under 60tkm (both vehicles) from 2010 (unfortunately without a heater) (both vehicles are running for about 60tkm) with a BSE engine from 2007, running almost 72tkm, oil consumption available but not dramatically high according to the previous owner. The Maxi would be attractive, but as a second car the vehicle is moved almost only short distances (< 10km, every 1-2 months about 120km highway) and the stopping time should be again "to the bitter end", as easily and cost-effectively as possible natural. What do the experts advise, how would you decide? Thanks and greetings, Chris
