Help!

I've been looking for a nice set of rims for my car.. but I'm not sure what size, bolt pattern, etc will fit my 05' Honda Accord. This may be a dumb question but I found a set of 18" universal 4 lug rims.. but my car is 5 lug (I know that much! ha.) Does that mean they won't fit my car? and are 18" too big for my car anyways? or does that just depend on the kind of rim & wheel?
If anyone can give me some advice about all this, I'd appreciate it! :)

correct... don't even bother if you got the 4-lug rims... re sell them

I didn't buy them(thank goodness) but thanks!
