Better to start with a unmodified car that has never been hit and then have someone very reputable modify it to your specs. That way you will have peace of mind and some real confidence in it.
They listed a lot of parts and mods, but unless the guy who did all the work is really really good and all the parts were actually new and not taken from another crashed 'replica', it could be just a money pit 'project' car. You don't want to spend big money sorting out another guys mistakes or replacing used parts.
Just looking at the picture and the advert specs, I bet it will need wheel bearing, wheel hub carrier, half shaft and differential work soon because there was zero mention of parts upgrades to compensate for the bigger rear wheels and tires and power upgrade.
Also the rear wheels look like they have neutral camber or slight positive camber, probably because there is not enough adjustment left in its non GT2 suspension to get a small amount of negative camber dialed in with the bigger wheels and tires. Maybe I am wrong but from the screen that's how it looks. With a different suspension kit and rear arms that could be fixed..... Money fixes everything.
