I've read the posts from beginning to the last and its amazing how the topic has changed so much.
Anyways to get back to the original subject regarding the price of new sedans to come. The fact that there are new high price kits to be released means that there is a market for such cars. By that, I am saying that there are a considerable amount of people willing to pay $400 plus for a new electric sedan chassis. Manfacturers are not pricing these things to hold the hobby for ransom they are doing it to meet the Demand!!
With that being said, those kits are not the only thing available inorder to have fun in this hobby. You can also choose to go with the lesser priced kits and still have fun and be competitive as well.
It is not about what you have, it is about what you put into the hobby in the form of effort towards tuning and driving ability.
Now about being better to buy all the options at once instead of doing it piece by piece. Sure its better and cheaper in the long run to do that but not everyone can afford to. This hobby was built by the average guy starting small and building up as he is able to afford it so there should be nothing wrong with starting from a low or medium priced kit and building from there.
And about the body issue, I don't know how many times I have seen this but there have been a few times at SoCal where I saw someone run a truck body and beat the entire grid by a lap or two. Go figure
To anyone new looking at this thread, pic a car that is well supported in parts and service at your local track or hobby shop, stick to your budget, buy only necessary accessories to help you tune the car and have fun.
