40,000 for a 1.5mil car. No. This update is a boring grind. It's a waste of time. Not worth it.
Dude, you've complained about this twice. You make $100,000 minus $20,000 for mods. Seems you don't read properly when selling.
Also, it's not about it being a "1.5mil car". It's a 10 minute or less mission. Spend about 30 sec going through a menu customizing the car then drive a supercar from point a to point b with nothing to worry about besides jet griefers and NPC traffic.
Frankly I'm a good driver, the NPC traffic is nothing, and somehow I've been very lucky and never griefed on a sell mission. Selling cars in lower populated public lobbies is easy money.
