Car pulls to one side

[Paul A]

I have recently bought a 2013 Astra Elite 1.6 (1st Registered December 2013), it was 9 months old when I purchased it with only 2,600 miles on the clock. The car drifts to the nearside and the steering wheel is off centred to the right. The car has been back to the dealership x3 times and I am told the wheel alignment is spot on. I am also told as the car has 18ins wheels fitted (factory fitted), that is the reason for the drift to the nearside - all Astra's with 18ins or 19ins wheels drift to nearside! I contacted Vauxhall and the car has been inspected/driven by a Technical man. He has stated there is no problem with the car and it 'drives as it would be expected from the factory'. Obviously, I am not happy with the situation and would welcome some advice from anyone who has experienced this problem please. A new'ish car like this should not, in my opinion, drift to the nearside. Any help would be appreciated.
