looks pretty shot... but definitely fixable... consider that you will need to have rust repaired anyway on any shell so if you take the cost of a shell ($1000 + rust work) you may not be to far off saving this one.
You do pay for quality sam... IMO metal is always better then Composites for a street driven car (unless it was engineered to be made up of composite).
peter do you already have the kit??
There are much better coilover options available these days that are base height adjustable, the weld on coilover sleeves dont have a whole lot of adjustability.
heres a little tip.
Don't add any relays or extra wiring until you have the stock system up and working 100%. All you will do is introduce more problems to an already faulty system.
