Nord Auto SIA - Ainars Aboltins - Unusable Audi Q7, with a destroyed engine

We bought the audi q7 from the car dealership Nord Auto Sia in riga and made a contract with this company.
The situation is, that the salesman says, that the car is in good condition and checks in the car service. In reality, the car is very broken and the engine is out.
The biggest problem is that the engine pistons shake, and the cylinder is worn metal debris is in the engine and engine oil. The air conditioning system is broken and the pipes are damaged.
Various links, rollers, belts, etc. Are critically worn. But the biggest problem is that this car is unroadworthy. Mileage has been rolled a lot down, in Estonia, it is not taken this car into account.
This car dealer cheated knowingly.
New, fresh oil had been put into the engine, a very thick composition, that the clatter of the engine would not be heard. Such oil should not even be used in the engine.
The oil pressure sensor has been modified, removed from inside the meter, and put back with glue. We opened the engine and it was fully destroyed. We offered the car back, but they lacked interest. With a lot of trouble, we got a small compensation for the block, but they turned their backs on repair work and service.
Now, the car is almost done and the repair invoice has an additional 8000 eur.
We should go to court to recover damages, but we recommend staying away from the others. You can easily cheat.
