Yes it's a mustang gt500 designed by sheep on youtube.  Hardest part was the functioning brake pedals.  Very complex and hard to get just right, took almost an hour
OMG I LOVE TECHNICS!  Do you have a pic/vid of the functioning brake pedals?
I have this set--I think it was the only Technics set my dad would let me buy:





I absolutely loved building it!  You had to build the engine block, crankshaft, the pistons, the timing chain, and the steering rack.  In fact, I remember I even have one of the power modules that looks like a long stick (hope it doesn't have batteries in it still  

) and even connected it to the dragster as you could to make it powered.  When it moved, the pistons move up and down like a real engine.  I was always captivated by how things work and this kit was my only exposure to that.  Who knows what I would have done in life if I would have had all the Technics sets I wanted...
This was my dream set back in the day:

And now that I'm older and my birthday is coming up, I need to get myself that toy I always wanted...
There is even an RC version, but that would have put it in the 1000 range YIKES!  
WOW!  But that's actually not a bad price considering any decent RC car was $150+ back in the day (I have no idea how much they are now.)
