My 2010 1.6 Doblo Maxi van has around 108k miles, mostly done before I bought it, so I cannot claim long term experience of it.
Faults I had to rectify were, oil cooler leaking oil into cooling system (this damaged any coolant seals it was in contact with causing them to swell, so if disturbed for any reason they had to be replaced) I would say to fit the oil cooler at the back of the engine was a pain, not helped by two faulty new oil filter housing assemblies. This problem meant as soon as engine started, oil would drip from the oil filter drain valve, the idea of which under normal conditions is that when changing oil a hose could be fitted to this spigot to avoid mess, so that after a few turns releasing the oil filter cap nut it should open this valve allowing the oil to drain from the hose, instead of which it leaked permanently.
At around that mileage the turbo bearings failed allowing oil into intercooler and inlet manifold (blue smoke), I fitted a replacement turbo cartridge which was pretty straight forward.
I also had a black smoke and limp mode errors etc. which turned out to need a replacement seal where EGR pipe joins inlet manifold to cure that, so could have been worse.
Another common fault on many Fiats was the top strut bearings seizing and needing replacement.
In fairness I bought the van cheaply after it had been standing for many months (which didn't help those top strut mount bearings) as I suspect the previous owner (double glazing company) thought the head gasket had gone due to the oil in the coolant tank.
I do have to look at 1st gear engagement which requires a positive push, more than usual.
Being retired I have a habit of buying vehicles with known faults, supposedly cheaply as a way of relieving boredom. As I never sell for a profit some would say I should find another hobby

If you have had the vehicle for a long time and regularly serviced it, I would stay with it.
Personally my main complaint is for a alleged 105hp engine fitted to a van with a 1 tonne payload it's bottom end grunt when pulling away is much less than on my 1.6 diesel Citroen C3 that has over 220k miles on it.
I have just bought a 2010 Scudo 2litre with a light rattle and misfire etc. from around the top end, so some would say I never learn, including my children, so I tell them I am spending their inheritance
