Added to @CrazY code, after cost you can add Team and check for specified team, not precache multiple times, i think this is better

something like this

#include <amxmodx>
#include <fun>

#define TEAM_T	1
#define TEAM_CT	2

enum _:ModelData
{
	NAME[32],
	MODEL[32],
	COST,
	TEAM
}

new const Models[][ModelData] = {
	{"Name to show in menu here", "folder name inside cstrike/models/player", 2000, TEAM_T},
	{"Another model", "folder name inside cstrike/models/player", 3000, TEAM_CT},
	{"Another model", "folder name inside cstrike/models/player", 4000, TEAM_CT|TEAM_T}
	// add more models
}

public plugin_init()
{
	register_plugin("Plugin", "Version", "Author")
	register_clcmd("say /models", "CommandSayModels")
}

public plugin_precache()
{
	for (new i = 0, buf[128]; i < sizeof Models; i++)
	{
		formatex(buf, charsmax(buf), "models/player/%s/%s.mdl", Models[i][MODEL], Models[i][MODEL])
		precache_model(buf)
	}
}

public CommandSayModels(index)
{
	ShowModelsMenu(index)
	return PLUGIN_HANDLED
}

ShowModelsMenu(index, page=0)
{
	new menu = menu_create("Models Menu", "HandleModelsMenu")

	for (new i = 0, buf[56], len, info[3]; i < sizeof Models; i++)
	{
		len = copy(buf, charsmax(buf), Models[i][NAME])

		// if the player doesn't have that skin, add the cost
		if (has_skin == false)
			len += formatex(buf[len], charsmax(buf) - len, " \y%d$", Models[i][COST])

		num_to_str(i, info, charsmax(info))
		menu_additem(menu, buf, info)
	}

	menu_display(index, menu, clamp(page, 0, menu_pages(menu) - 1))
}

public HandleModelsMenu(index, menu, item)
{
	if (item == MENU_EXIT)
	{
		menu_destroy(menu)
		return PLUGIN_HANDLED
	}

	new info[3]
	menu_item_getinfo(menu, item, _, info, charsmax(info))
	menu_destroy(menu)

	new model_index = str_to_num(info)

	if(Models[item][TEAM] != get_user_team(index))	return 1;

	// do something with model_index

	return PLUGIN_HANDLED
}

how's this related to the problem ?

[CrazY.]

I think you misunderstood the meaning of T.mdl
It's not a "team" model. "T.mdl" is a packed texture used by the main .mdl.
In most models, the texture is compressed along with the main .mdl so there's no T.mdl to precache, but in the case the file exists, you must precache it. That part of the code you deleted does check if the file_exists before precaching it, not sure why you deleted it.

Anyway, this is completely off topic and irrelevant to the main issue, which honestly I don't understand until now.
