Well true,i guess someone who has got it done or plans to do so has to throw some light on this, are they changing the springs with different load settings or any other method,but the diesel should be the more expensive one not the petrol,or the petrol model needs something extra than the diesel or the pricing mite be wrong,anyone who visited the dealers got any info? My friend should be getting it done for his Punto(his car has seen alot of bad roads) this week,probably will go along with him check it out for myself.
