The T30 was actually produced in 2 series. The first series was all white in colour with leather trim. The full compliment of 30 were produced & were distributed to the top 30 hsv dealers across the country. The build number was the ranking of the dealer. These vehicles were never available to the general public as a new vehilce. The dealers were required to keep them for a minmum of 3 months before being able to sell them
The Series 1 was rated at approx. 180kw & featured all the luxury comforts with momo accessories.
The 2nd series was released in 91 & was modelled on the series 2 vn berlina with all the powerpack options. This was in the time of a reccession in australia & only 10 were actually produced, not the full 30. This series was a 2tone blue with the running gear of the sv5000 & mild body accessories. As with the series 1, the car featured the dealer name pinstriped on the bootlid & the dash badge also had the dealer name & number. The no. 1 vehicle in this series was an extra special vehilce as it represented the 5000 hsv produced from memory.
All in all the T30 or Top 30 HSV is somewhat a rare vehicle to hear of & find & even most dealers aren't even aware of what it is.
