Ok first thanks for the thumbs ;)
I can understand you buying the items in an other order and you're totally right with it but this build is not like "You have to buy it in this order or you will lose", these are just my item preferences and you can turn the build upside down if you want. The thing with thornmail is, I like it very much against really strong AD carries like Tryndamere but normally you will get enough Armor by the other items. And the cool thing about Sunfire Cape is that you are going to destroy a minion wave with one use of Judgement (think I wrote that in Items Section). I'll add the Greater Seal of Malice :D thanks for this tip

Decent guide though I would like to say something about it.

I love playing Garen as a tank, but in a slightly different order. For instance when I take sunfire cape I feel like I'm doing a more kind of damage built with bit tanky in it. I would take Thornmail over sunfire cape as tank anytime. Also I would advise getting atama's impaler faster but that's just a personal thing I guess :p.

Also you might want to add like 2 builds in this area for like only armor and one for only Magic resist (just a side thingy).

For runes you might want to add Greater seal of Malice. It's awesome for your judgemnet skill.

Also I think ghost with exhaust works better. The reason for this is, if you use your Q + ghost you gain massive speed catching up with any character that runs away. And exhaust works awesome with your judgement skill gaining the full damage it could give.

For the rest it looks decent *thumbs up*

And my english isn't awesome, sorry for that :P

Ok I'll add them and you're right if i want to see how other people build a champ I often just get a quick overview too
And THX

You forgot to put the upgraded boots in the cheat sheet :P

Edit: After reading a bit, you did it on purpose? Well, many people don't read and just use the cheat sheet soo... I suggest you add them anyways ;)

Looks good.
