Im pretty sure I read that car had nitrous on it at one time also. You doing work yourself? Your estimates seem low IMO.

I dont know what it needs for a stereo, if you end up paying a shop to install a deck/speakers it will be more than $200

The brakes to swap in with Used AMG stuff im sure that will cost you $300+/with pads if you look and do the work yourself

Respray for $150? That seems quite cheap IMO to have a quality job done, but why respray a non srt-6 bumper?
Then you have to do something about those hidous wheels.

I have seen SRT-6 seats sell on ebay at 600 on up + shipping for the pair.

Wouldnt you be better off finding a coupe for $15-16k and be done with it?

I figure SRT-6 seats $700+
Deck $200 installed
Does it need speakers?
Bumper? Id replace with SRT6, woudlnt mess with that reg bumper. That + paint = $500+
Wheels/tires = $1000+
Brakes Front $300+
Brakes Rears $200+
Reg maint. Oil+ filter = $80+ DIY/200 dealer
12 spark plugs = $30-$80

I see 3k right there easy just to bring it up to "non molested" status and that doesnt include an SRT-6 wing that cost $1200 from the dealer.

All for a car that sounded like it was beat pretty good when an original SRT-6 can be had for almost the same price. No thanks. You may view it as $3k+truck+extras but what can you sell your truck outright for?
What does Truck sale +3k=?
What does Truck sale +3k + 3keasy in "repairs" =? Could you buy yourself a $15-16k crossfire with that?
