Story: Due to the Oil crisis of 1973, HTA was in financial trouble. As most of their models had to be discontinued on that year, And with the colonial as the only Model they were producing on that year.
HTA simply couldn’t compete with the cheaper, more powerful and more durable japanese cars of the era.
on the verge of bankruptcy, HTA contacted with an old japanese engineer.
The result was this: it was the most sold convertible on that year. as it was comfy, cheap, durable, and with a good fuel/oil consumption.
