From TL-01 to TT02

I own a Tamiya TL01 that has been my car since I was a kid. Over the years, I’ve also bought many spare parts, from gears to springs and dampers, as well as a carbon fiber transmission. I’ve seen the TT02 on sale at a decent price, and I’m considering switching to this chassis (I use it mainly for fun, not for competition or anything like that), especially because it looks a bit more modern and refined, and seems less prone to getting dirty after a run on the street.

I have a few questions about this potential switch:

1. Is it worth the upgrade? 2. Is the TT02 able to support a brushless motor? 3. Of all the spare parts I’ve bought for my TL01 over the years, do you know which ones are compatible with both chassis? 4. do you have a basic ESC, modern battery and maybe even basic brushless motor to suggest (i prefer battery life vs overall power)?
