to be honest the badging dosnt mean alot, ive seen alsorts of gti's (mk4 turbos) some with silver (all) some with a red i and other variation, they are now at a stage where the badge means jack shate!!!,
there are:
125 bhp normally aspirated mk4 gti's 1800 cc (20v)
115 bhp normally aspirated mk4 gti's 2000 cc (8v )
150 bhp turbo charged 1800cc (20v)
180 bhp turbo charged 1800cc (20v)
then theres also
150 bhp v5 2300cc
170 bhp v5 2300cc
204 bhp v6 2800cc (v6 4 motion)
240 bhp v6 3200cc (r32)
there is many guises and many badge variations so no one can iddentify alot now, ive seen v6 4 mo's with gti (red i ) badges on.. unless you can see whats under the bonnet and rely as to whats a original model i cant say anything for sure
and then i forgot the turbo desiel gt models...
115 bhp 1900cc tdi
130 bhp 1900cc pd tdi
150 bhp 1900cc pd tdi
