I am looking to buy a reliable and cheap touring car to start on my club track.
I own an AE B5M and a Losi XXX SCT.

I was initially thinking of a Sakura XI Sport but not sure it will be enough reliable and I do not want to spend time replacing part. I know AE products are usually good.
XRay TC14 is out of budget.
TT-02 is less attractive than AE TC4.

How reliable is a TC4 Club Racer out of the box?
Is TC4 Club Racer closed to End Of Live ? Or will it continue to be produced?

What are the parts to change to make reliable? Front CVD ? What else?

Thanks.
