A1 Performance Solutions A6 Performance Solutions A1 great way to be scammed..... by car dealer Internet

I bought a car from A1 or A6 Performance Solutions and the moment I drove it home the car started producing excessive smoke and dripping oil/petrol.  Called dealer who asked me to bring the car back to him, which I did and he informed me that the turbo had gone and it would be repaired or he would give a refund.  When I bought the car I was informed the car was in excellent condition including the engine and a new turbo had been fitted.  I later found out that service documentation supplied for this car turned out to be fraudulent and not for this car.
 
The car was left with the dealer for repair
 
During the weeks that passed there was one excuse after another as to why the car had not been repaired (I had to telephone them as they hardly ever contacted me with an update).  He told me he was still waiting for the turbo. After a number of weeks of hearing this excuse I contacted Mercedes who said it was in stock.  When I relayed this back to A1 Performance Solutions I was informed that they had ordered it from Germany to save on costs and once replaced the car would be as new. He told me on one occasion to stop wasting his time as he had other customers to deal with and he was repairing the car out the goodness of his heart.  On another occasion that he had seen the Turbo been replaced but only later for me to find out it had still not been done.  On another occasion that the computer was being reset. And on another occasion he also told me that the gearbox, head, cooling pipes and headlamp have all had to be replaced. Eventually he very nicely told me to F*** OFF.
 
Finally after months of chasing the dealer I threatened legal action and then A1 Performance Solutions goes out of business only to setup as A6 Performance Solutions.  They had the car for nearly 3 months
 
I had to get the car towed as the dealer has removed the original Turbo and refused to return it.  I am facing a large repair bill to put right what should have been done by the dealer. Please be careful when dealing with this dealer
