Evra Motors Ltd - Not Recommended - Breakage, bad service

So i would not recommend the garage evra! Not a good seller, not honest. Two options: 1. They hid and not say the problems of this car or 2. They did not do any car service. About two months after the purchase, the engine is gone. The seller 18/07/2018 gave a warranty of 3 months or 3000 km. The warranty indicated the mileage of a car 150,000 km, the nct test 15/01/2018 recorded mileage of 150025 km. It turns out that over 6 months, mileage decreased. Where it starts and where the warranty ends is not clear. It was also said that the full service history from mazda. I was in mazda last record 28/10/2015 (75576 km) . The final result of the repair: crankshaft + big end brgs + 4 injectors + oil pump (i will not speak about small details) .
