Sounds a little high but tough to tell really w/o exact details of what will be covered.
For some comparison:
2003 Corvette Z06 - had 2/3 of the hood (including pop headlights) the entire front bumper, 2/3 of the front fenders, & the mirrors done w/ Xpel ultimate + tinting 3 windows = $1400 all in, that was 5-6 years ago.
Had my 2018 Ford Raptor just recently done, did the grill/light surrounds (any plastic/painted trim on front end excluding front bumper), "large" partial fender coverage, & "small" hood coverage (like the equivalent of bug shield size 4") + the 4 black plastic b-pillar (not sure if right term) door trim pieces in Xpel ultimate, + tinting front 2 windows in ceramic to match the rear = $680 all in, that was like 3 weeks ago.
Both times the installer was a very high end reputable shop.
You do not need "paint correction" on a new vehicle prior to doing this, if anything you'd sorta wanna do the opposite from what I've told if you want it to last a long long time. You SHOULD claybar the entire vehicle, maybe even twice on a new vehicle if theres alot of rail dust or an older vehicle w/ alot of tar/oxides, then alot of installers use dawn or some other alcohol based solvent that will REMOVE any and all paint/polish prior to installing the PPF. This way the PPF adheres much better & the claybar is a preventative measure to get any unseen specs of dirt/dust/tar/sap & eliminate any residues. Some installers do wax the vehicle prior to install.....so the film is easier to remove down the road.
Do you want the PPF to be more easily removed? Don't think so.
Lastly, in terms of performance, my wife literally backed her MDX up & over the front bumper of my Z06 when her foot slipped off the brake in our tandem style garage. There were DEEP gouges in the film as well as heavy smudging/rubbing marks of plastic (in the pic it looks like shadows of clouds but is actually smudged rubber) & I was praying the paint was fine underneath....well after a couple pours of scalding hot water, sitting in son, then a buff/polish by a body shop & the gouges nearly disappeared (see attached). Also - had a heavy rubber chaulk block fall off a truck on hwy tumble down road & SMASH my front bumper on vette right around where the intake hole (where fog lights are on non Z06 models) - again, the rubber smudged buffed out, & miraculously no damage to the plastic bumper except for the smallest sliver of a crack in between where 2 pieces of film met - in other words, without the film the bumper would've certainly cracked & required body/ins. work.
Hope that helps.
