At the end of the day its a convertable celica and looks ok for what it is.
Your opinion is very OTT since the car is not a GT4, and never was a GT4, so surely cant be compared with a GT4.
Toyota made plenty of Convertables over the years, and lots of companys convert normal cars into convertables. Both will add sufficient strengthening to chassis to compensate for the loss of the integrity the roof provides.
Not sure what your problem is Baz?? It a reasonable looking celica soft top and certainly dosent warrant your OTT description.
Nuff said. Over and out.
