About “GRTWHT”

This is my latest addition to the garage. It is quite rare being 1 of only 73 delivered to Australia in 1981, now 26 years old and in great shape. It was been well maintained by the previous owner. I have changed out a few items that were worn out on the car since owning it, I found these out because I drive the car like it was designed for, but it was nothing I wouldnt change on any other car. I'm forever cleaning this car, everywhere.I drive the car alot, and beleive in 'Drive it dont Hide it'. I have clocked up quite a few miles since August 2006 without any problems, it is my everyday car 4 days per week, and on the weekends for a run out in the country. It has so much grip, fantastic for high speed cruising.
Super Fast,smooth,agile,classy,agresive. It just drives beautifully.

About “Silver Thunder”

This car is one of 4212 Super Coupes produced in 1992, of which 2956 were automatic transmissions.

I bought this car in nearly stock form in 2003. It was a little rough, appearing to have been taken on an off-road adventure which left the front bumper cover damaged. It also showed signs of wear with paint flaking and numerous door dings. I have since tried to remove all body damage, and modify both the appearance and performance of the car. There are, of course, more modifications to come for both. The cosmetics include the first ever made Cobra R hood with ram air for the '89-'93 Thunderbird. It also sports a Xenon Air Dam for a '94-'95 Thunderbird capped with motion sensors to protect the bumper cover from curb-stops, speed bumps, etc. It was featured in stock form in the 2005 Super Coupe Performance (SCP) MN12 calendar as the January car. It has again been selected for the month of September 2007 SCP calendar.
