Yeah, this has been up before.
I've got one of these t-shirts and it's slightly annoying that it's not accurate.
It says Haynes Manual Golf GTI - then gives the 1.0 and 1.3 engine sizes
The dates are wrong for the Golf GTI, which only came out in 76.
The engine in the car is clearly an 8v, but the "exploded" diagram at the bottom (in pink) is a 16v engine
What else have you spotted ?
