I need ideas on what to get my because for christmas he is 24 and car mad and fishing mad I need ideas if you have any?

What things does have already have that have to do with cars and fishing? That way we know what to rule out. :)

OK he has a good car stereo with amps and tackle for fishing and a rod I was thinking of getting him car seat covers

That sounds like a good idea! Get him some car seat covers and maybe a steering wheel cover to match. I know they have those items available in the "Mossy Oak" theme, does he like Mossy Oak?

You could also get him some little "filler" things for his tackle box, such as weights, floats, hooks, etc. I have a lot of friends that fish and they tend to lose that stuff at times and have to go buy more.

How about a really nice car poster or something? Even maybe one that's been signed.
My ex was carzy about chevys I bought him a chev model car a chev banner a chev watch and he was rapped with it.
I found all the stuff on Ebay.

Its err a bit late but what about some car stuff like an airfreshaner or stuff!
