welcome to the forum. ive only been here a couple months, but the guys here really know what theyre talking about and are willing to help you out. so far, from what ive read on here and experienced with my v8, main problems are coils, valve cover gaskets, and window regulators. all of these can be fixed by you if even if you have little mechanical knowledge. there are also write ups for them, if you need help.
even though ive had problems with the coils and had to replace the valve cover gaskets, (which i did by myself, and im near mentally challenged when it comes to cars), ive never regretted the purchase.
