Around what level should my Pokemon be before facing the Elite Four in Platinum?

Question

Right now, I just beat the Sunyshore City gym and defeated Volkner.
I'm currently on the way to Victory Road. My Pokemon are:

Torterra Lv.45
-Rock Climb
-Crunch
-Earthquake
-Razor Leaf

Giratina Lv.47
-Fly
-AncientPower
-Dragon Claw
-Shadow Force

Gallade Lv.43
-Psycho Cut
-Drain Punch
-Cut
-Leaf Blade

Houndoom Lv.44
-Sludge Bomb
-Flamethrower
-Faint Attack
-Rock Smash

Rotom Lv.42
-Thunderbolt
-Confuse Ray
-Uproar
-Ominous Wind

Floatzel Lv.43
-Crunch
-Waterfall
-Strength
-Surf

Are my Pokemon good so far? Are the moves good right now and are the levels I feel like I'm underleveled but I don't know good places to train.

Answer 1

I suggest levelling up your Pokemon to Level 55 (or level 50 if you want a bit of a challenge), since the champion uses Level 58s, 60s, and one 62. And your team looks awesome.

Good training spots? The wild Pokemon in Victory Road actually work pretty good for training, and there are two trainers (Fisherman Cole, two Lv. 41 Gyarados and Beauty Nicola, one Lv. 45 Lopunny) on Route 222 who have Pokemon who give great amounts of exp.

Good luck ^-^

Answer 2

I understand this post is old, but just posting on this to help a future gamer who is looking to challenge the elite 4 early. I challenged and defeated the elite 4 as well as Cynthia with a entire party of Pokémon in level 40s, the highest being 49. It was tough and needed the use of replenishing items in between battles, but extremely fun and very possible if you wish to challenge the elite 4 without much training.

My team consisted of Infernape (level 47), Garchomp(level 49), Staraptor (level 44), Gyarados(level 43), Luxray (level 45) and Abomasnow (level 41)
