i own a 16v gti and an edition one g60
id say value wise the 16v is the best bet , its got enough power to be fun , but good on fuel and theyre reliable , common enough for spares etc
the g60 has a bit more power , few differant bits from the factory like strengthed chassis legs and the high tunnel , bonded screen etc , but theyre a bugger on fuel and the charger needs coslty servicing, the lhd doesnt bother me a bit though
