There is a problem with rear view visibility from the drivers seat with the top up. The rear seat head restraints all so block vision out of small rear window. The Toyota body is not stiff enough with out the unit body roof, this makes the convertible a bit unstable on all but super smooth road surface. You get a lot of shake car needs improved body supports.
It is fun to drive with the top down.
Improve body role and shake. Improve rear view visibility.
