Is the 1.6 EcoBoost reliable?

It is a turbocharged direct-injection four-cylinder that Ford used between 2010 and 2018 as a mid-range step across much of its European line-up, and which Volvo sold under its own T3/T4 designations. Its most serious fault is overheating caused by a loss of coolant circulation that can crack the cylinder head and cause a fire: Ford has recalled cars in South Africa and in the US/Canada, although we have not confirmed an equivalent campaign in Spain.[1][2][3]

Is the Rover K-Series reliable?

The Rover K-Series has one very well-known fault: the head gasket, which according to Diariomotor can fail at under 100,000 km and which technical sources link to a small cooling circuit and a badly placed thermostat. The usual repair uses the multi-layer (MLS) gasket developed for the Freelander; the other two documented faults (sunken liners and coolant leaks) are related to that same circuit.[4][5][6][7]
