It has the Recaro's which are nice, but the wheels look like the non-turbo ones, so I'd guess that to be the 125 bhp 1.8 20v GTi (Non-turbo).
Only clear way to tell, is to get the engine code off the seller. This can either be got from the previously mentioned sticker in the spare wheel well (in the boot), or from the engine itself.
If you want any half decent amount of poke, tho, I'd recommend a turbo model.
