I'mGlad all is good.

(I'm assuming it is full coverage by the description)

Due realize though,  blue book could play little factor in this. They need to pay you "real replacement value"

In a 5 minute Craigslist search I did not see a single spark valued under 8k and some as high as 12k. Now I don't know the spark market or the condition/trim of yours but if comparable to the units I saw you need to print out any unit you find for sale in comparable condition normally 1 model year older to 1 newer and as much as 25,000 miles either direction on the odometer. 

If the insurance low balls it provide them your findings and explain to them you want the same car and must be provided enough to get a like replacement at current sales rates

As you probably know I am/have gone through this currently

My insurance is for stock vehicle so forget my mods 

Kbb is 14-17 on the Jeep after talking with the insurance some and having some print outs of if I went out to buy a like replacement today here is how much they are going for info you may be able to increase that (craigslist, dealers,auto trader ect). Because of what the vehicles are actually selling for I got somewhere between 155-170% of what the value Kbb said. 

Again this all depends on condition/trim of the car but my quick search showed you are going to need allot more to buy that vehicle again (even if that's not what you want)

I know this whole process can be a pain but check going rate for that car in this area. Maybe it's less and your getting a good deal with kbb value but maybe your getting screwed and need to throw kbb out the window (its what I did)
