Hello, I was looking for some help and information on the : Subaru Impreza 2.5 WRX 5DR , 2008 , the new shape.Firstly, are they a reliable car and not hugely expensive for parts if they do go wrong ? Are there any known faults or problems with them ? I have had a few problems with my T180 Rav 4 which just recently Toyota put a free new engine in. Parts are more expensive than the V W's I have owned ! Looking at buying one as they seem a great car. Thanks for your help.
