I have suzuki cultus VXR 2004 model. Recently i changed it's tyres n inserted 2015 model rims along with radial tyres. When i went to a mechanic for alignment (i visited him for the 1st time & don't know about his credibility). He said me that i must go for the suspension work of my car as soon as possible. Wheels' bushes r broken n many other things need to be replaced. Although i just don't feel any trouble while driving the car, not even a little bit. Plz guide me how can i exactly judge that should i go for suspension work or not??? He gave me an estimate of rs. 6000 work & for almost 3 hours.
