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 2.3 MZR DISI Turbo reliable?

Mazda's 2.3 DISI Turbo (L3-VDT, 2005-2013) is powerful but demanding: the timing chain, the turbo and oil sludge are its weak points; only buy one with a good oil service history.[5][6][7]
