OP, if you end up with a Z06(i hope you do) and interior starts to bug you like it bugs me...these type of sales happen all the time over on CF.com
I've gone ahead and purchased DSV steering wheel, console lid, tunnel drapes, shift knob/boot and ebrake handle/boot. All under $1800.
That still leaves the seats(about the worst seats ever put in ANY car). My plan for that is to get Caravaggio race seats which will be heated(race and heated, da fuq right?)...the seats will run me about $3k shipped, maybe a bit less.
So interior will run me about $5k, well thats a lot but not really...but after i upgrade these pieces my interior will be right where i want it and wont have any complaints
