Alfa 155 and Lancia Delta Integrale has always been my great heroes; these cult cars share one of the most aggressive and race styling, both dominated race tracks and even civil versions are delighted with magical reputation. Somewhat Alfa 155 Q4 is more desirable of the two, because the ultimate  combination: Alfa's impressive styling, racing reputation in DTM and Lancia's heart developed in rally.

Alfa Romeo 155 TI.Z (International Tourism Zagato) and GTA.Z are very rare and special models of the range topping Q4. Alfa 155 is designed by Ercole Spada (man behind some iconic designs such as BMW E34 & Fiat Tipo) while working in Zagato.  Together with race engineer Giuseppe Bizzarrini guys developed TI.Z and proposed it for the production. Unluckily this aggressive styled masterpiece with performance to match didn't fly and TI.Z/GTA.Z's ended up for a very limited production funded by Luca Zagato himself and bunch of Japanese businessman.
