The ad appears to have "ended." If still for sale, I'd be very careful buying that car/checking its history/provenance:
1) As it says in the ad, its a "Stingray" (466BHP) with a German made (why?) bodykit. Its not a widebody 650bhp C7 Z06.
PDR700WB Widebody-Kit für alle Chevrolet Corvette C7 Modelle beinhaltet: Frontstoßstange inkl. Frontspoiler, Frontkotflügel inkl. Kotflügelensatz, Seitenschweller inkl. Schwelleransatz, Heckdiffusor, Heckverbreiterung.

2) The advert says it has the LS3 engine (C6 Corvette). It doesn't, it should have the LT1 engine.
3) Ad doesn't say what year it is? But looks to have the 8 speed auto that came on US cars from 2015. Steering wheel is round at bottom, not square as from 2016, so a 2015.
4) Ad doesn't say if it has the Z51 performance pack. Wheels look like Z51 (and coilovers been added to it).
5) Its a US car, but has headlight washers. US cars dont have them. Maybe because the bodykit is German and includes them (see their website above). Do they work work? But no problem anyway as car has an MOT?
As noted above, essential to have a US CARFAX report on that car. I would be asking Ian Allan/Parts USA what they can tell you about the car. But they probably won't re customer confidentiality/data protection.
