i got some KYB's and H/R OE sport springs installed on my car last year. I've put roughly 10K miles on them, mostly highway miles.

How much money do you think i could get for these if I were to sell them?

(FYI these shocks and springs are for 5th gen civic coupe - i assume they will fit a hatch, possibly the sedan?)

 

they'll fit any 5g civic... they'll fit 94+ tegs too, but they may be softer than is ideal for the heavier car.

It doesn't matter if they were used for a week or three years, once a part is used, its usually worth no more than half its original price.

 

so lets say i bought a brand spanking new SC61 turbo for $650,..i throw it on my car for one day and the motor cant handle the boost and it scatters,...so now i have this blown motor and i have this SC61 turbo that was driven no more than hmm lets say 6 miles,..now you are saying i cant sell that turbo for no more than $325? fuck that

 

I was making a generalization, hence the use of the word "usually"

In my experience selling crap, it takes a low price to get a ready, willing and able buyer for used car parts. Unless people know you or you have good references, they're not gonna trust the "it was only on the car for a week" shpiel... Thus the amount of time it was used really doesn't matter, although condtition does. Now if you don't mind if it sits on the market for a while, or if you've got a bigger market to work with in the first place, thats not always the case.
