rear axle damage on 04 XL7

I was recently in an accident where I hydroplaned did a 360 hit a light pole and went into a ditch on the interstate doing 65mph. The insurance company doesnt want to total it because there is just rear suspension, axle damage and some cosmetic work on the driverside. But everyone that I have talked to says I need to fight to get ittotaled because it will never drive the same again. Does anyone have any advice for me, i would greatly appreciate any help, this is my first accident and i have no clue what to do. Thanks

It depends greatly on the shop doing the work, if they dont cut corners then it will drive like you were never in an accident... if they dont, youre stuck with a car that drives like crap. Unless you personally know the shop doing the work, i would try to have it totalled..... suspension work is very tricky and time consuming.
