2018 GT Aggressor with many upgrades and repairs

For sale is a 2018 GT Aggresor with around 230$ worth of upgrades. Originally cost 669$, the upgrades I have put into the bike are:

-65$ each 130$ total, Maxxis Minion DHR II front and rear tire.
-30$, Tubeless conversion. Tubeless systems eliminate flats for good and increase traction. I used slime sealant for the conversion
-20$, 780 MM alloy riser Bars: I upgraded from 700 MM Bars. Wider bars grant the rider enhanced control and balance.
-20$, Platform Pedals: The old pedals were some crappy plastic ones. These have pins to keep you on the bike and they are made out of nylon composite
-10$, Shorter stem: I put on a shorter stem, which places the rider in a better position
-10$, lock on grips: These are attached with screws instead of having to budge to get them off. The green color also fits nicer with the bike
-10$, Chain guide: This keeps the chain from slapping and making noise, and makes it smoother overall
-75$ Shimano Hydraulics(not pictured because I did upgrade later) More powerful brakes
-Basically free, Zip ties: I removed the C clips which always fall off for zip ties for the brake and shifter cables
-Free, removal of dork disk, plastic chainring guard, reflectors, etc: I took those off just because they look horrible and only add useless weight and serve no purpose

I also had the bike recently tuned up at dicks(original place of purchase) where I got a new chain, a new shifter, a new top cap, a new and upgraded bottom bracket, new brakes in the front and rear(including pads and cables), new headset bearings, and a new derailleur hanger. I only rode it once since the tune up. The tune up was free because I had the warranty, which cost 50$ at checkout.

Overall the bike is in good condition after the tune up, only issue is that the back wheel is slightly out of true, but it is quite minor, and even after the tune up, the shifting still isn't great, but it works fine.

My price is 495$, I feel this is fair because of all the upgrades, but do not hesitate to shoot me an offer, and we can negotiate a price. Also do not hesitate to ask any questions.
