Is the 1.0 PureTech reliable?

It is a simple naturally aspirated three-cylinder, but with two documented weak points: oil consumption through the piston rings, which Stellantis acknowledges across its entire production (2012-2016), and the oil-bath timing belt it shares with the 1.2. It is only recommended with a full service history, a consumption test and a checked belt.[1][2][3][4]

Is the M60 and M62 reliable?

BMW's M60 and M62 V8s have a reputation for durability if the cooling system is looked after, but the M62 carries two well-documented weak points: the plastic chain guides of the timing chain and, from 1998, the VANOS seals. The M60 suffered cylinder wear from Nikasil with sulphur-contaminated petrol.[5][6][7][8]
