^ Yes the mk1 had the red line round the grill instead of the crome. Yes it has stickytape coachline on the side and black on the back window. Yes it had these to mark it out from the C and CL models, But the GX and Driver models shared alot of the same look parts and interior excluding the side tape. What i ment was it did not have stuck on rear spoilers that had no engineering reason to be there, extra exhaust pipes that had no engineering reason to be there, Side skirts no engineeering reason to be there, the list goes on, infact like ford had at the time.
The GTI has always had similar looking models in its range through its lifespan, Its nothing new, The GTI only ever differed very slight in looks.
The thing is everyones saying how much the GTD looks like the GTI so what its always been like this since the 70s get over it, they have done it with every MK of the golf INCLUDING the MK5.
