Mehran problem :(

I recently had an accident with the mehran in which the right front tire got damaged along with the rim and with an internal part.I went to the mechanic and fixed up my car in just 45 min.I didn't go for the alignment and the car began to run smoothly and it neither pull on any side at all.The mechanic told me there's no need for the alignment if your car is running smooth and it doesn't even matter if it recently had been in an accident.
I then forget everything, but recently after a few days I realized that the front right tire was few inches back as compared to the left tire.I visit so many workshops in karachi and mostly every body said to me, you should not undergo for alignment, it might worsen the condition, ok but we can bring the tire back into it's position, but we will not hold any responsibility of what so ever kind, if it's get unbalanced.After getting dissapointed I went to the Suzuki motor's(the one at the share-e-faisal) and they inspected the car and they told me we'll charge at least Rs.7000 for that.I can't afford that much for such a little problem, then I found another local mechanic shop in my area, he charged me around Rs.300 and fixed the car, now my problem is solved.But it has created a new problem, that whenever I centered my steering, the car starts to go in the right side slowly slowly.The car is not pulling itself to one side or the other, but I have to keep the steering in a little bit around 10 degrees in an anti clock direction and the car moves in a straight road.I told the mechanic and he said it's all in your head.But it's not like that.I can clearly see the difference, but the mechanic just can't do better than that!

I am getting tired of visiting mechanic shops and being getting ripped off, by every individual.

*--What I want is that If I center my steering my car moves in a straight path, as it used to go before the accident.
but what is happening that a steering is tilted around 10 degrees in counter clock wise direction to move the car in a straight road.Even though the mechanic had opened the steering to get it's fixed, but still there's some error, which is not getting corrected.
