Gaz's is a saloon, silver one debadged on CHs. Nobody has a clue what it is
I think the engine is under-rated, it doesn't make sense them being so fast for an 1800kg+ car. Kick the suitcase of a rear 'zorst section off too and they sound absolutely insane.
They've got some pretty trick kit, Sachs gas dampers, quicker 'rack, all ali suspension and that Golf R version Haldex - they actually handle quite well for what they are.
