What model and model year? There are some YouTube reviews of the G90 that speak to a top shelf car.
On the other hand you can go and pick up a 2013 Equus, loaded, with 60K miles for ~$22,000. That's leather, sun roof, 5.0 litre V8, Heated/Cooled/Massage, heated streering, 4 way camera (360 degree view) etc...
That's a lot of car no matter which way you look at it.
