One of my favorite quotes applies perfectly to this thread:

Perfection is often the enemy of progress.

If there are free mods available to you, it doesn't matter if you're not in "tip top" shape... the money saved by the mods may help you get into a financial position to fix things that need to be fixed, which then, of course, gives you the full potential of the mod you did in the first place.

Point being, just because you drive a piece of crap car doesn't mean you shouldn't be doing the free/easy stuff even before making the maintenance repairs it needs.
