Feedback and suggestion, not a moan! Tuners builds

Just a little awkward to find the right tunes at the moment, has meant me “wasting” credits on Cars which I then am bad in as I can’t find the right tune for it. So, to help others in not spending on unwanted cars, would it be possible to browse or have an area in game where players could browse the tunes of their favourite tuners? This may also help the tuners into doing more tunes as the would earn more credits by people browsing their “shop window” which in turn should encourage more tunes being built.
Also, I gather there is a limit to the amount of tunes that can be done and made available. Could this limit be removed? I appreciate the servers burden, but perhaps a 10 day “no-one has used it so it gets auto-deleted” could be done too?
Thanks!
