Following on from what others have said, yes upgrades are permanent and the the price in LTS always starts as very expensive option to get the car.

If you haven't tried winning a car yet, one or more of these LTSs would be an excellent opportunity to try. As KSqr said above, they are easy particularly if you do some bot management/slowing. If you do this, and even if you don't, winnng the car basically is only about time and having enough R$ and which can be found here. Winning cars in LTSs or Special Events (and Flashbacks when available) is almost always the cheapest way to get a car so i suggest you try to win as many as your time resources currently allow.

There's lots of excellent info on this wiki and many people who offer good advice.
