No, but there's no comparison between the Gen 3 Persona (factory 17" setup) and the Gen 4 Touring. I had to sell my Gen 3 Persona because the ride was so harsh and loud! Gen 4 Touring is fantastic ride.
The Gen 4 Touring models actually have a stiffer setup than the regular models. The Gen 3 Plus only had bigger rims and a quicker steering ratio.
Drive the 2 - there is no comparison. The Gen3 is a 2009 designed car and feels like it - at the time it was inferior to many other cars - I had a FOCUS and Gen3 felt a generation behind even when released. Gen4 is on the new state-of-the-art TNGA platform which has now migrated to the majority of TOYOTA vehicles. It transformed PRIUS as a driver's car.
