Did you take it back because of the cost of the Y pipe or did you not like the car itself?
The car was very good brilliant sound system ,nice ride and all the gadgets.The reason i took it back was that my kid didnt like it also it had slight knocking noise coming from N/s side at the front when i took it over a bump,i think it was a control arm or some thing .It also needed two new tyres.If it had only been the gasket on the exhaust i would have kept it,but with everything else needed doing i think i made right chioce in taking it back.
i have had Subaru for 9 months done about 5000miles only thing i have done is have it serviced, nothing has gone wrong.
