Yes, the eternal question. To mod or not to mod?
There are "non-performance" mods that everyone here would highly recommend, like a tranny cooler and 180 t-stat. Other things are up to you and your pocketbook. One thing point though, people will generally shy away from buying a modified car because that is usually a sign that it has been beaten the snot out of.
If you plan on keeping your car till it dies then I say, why not add a few toys on?
This is one car that no one expects to be stomped by! :P
