so i was going to work on a raining day, i slow down to about 20 mph,
getting on the hwy. on the curve i give a little gas. Starts spinning and
loosing control go down the hill and hit a tree. My driver's side rear
quarter panel and window are smashed. It doesn't look like I can just
unscrew it and replace it. So i have to take it to a body shop?
What are my options?

You just named them, do it yourself or take it to a body shop.

Time for some 50mm Rear Overfenders.

i agree, make it look alright and replace the window, then get the rear overfenders and mold them on, it'll look like nothing happend..

lol his second post, and its a totaled out story lol. Im sorry bro.

ouch.. sorry to hear that... get estimates from several places. You can also cut down prices if you look for used parts yourself and have them do the labor... (i.e. - salvage yards, ebay, used auctions...)
