Weighs 115kg less than your Grande (one of the reasons I disliked Grandes, they were incredibly heavy compared to older Fiats)..you'd imagine a fully loaded modern car that passes ncap would weigh more but no.
They are a sub 1 tonne car without a turbo. Having looked at the picture properly no rear discs, so no turbo (all PSA turbos get 4 discs)..so definitely a 73.
As the clutch wears it'll travel down the travel..so once it's knackered it'll drive better

. Actually in about 3 days you'll probably not even notice it, once the foot/brain adjusts.
Random PSA driving tip...to use hill start assist push the brake hard before releasing it..then gives you 2 seconds to find where the bite is before it lets you go. May come in handy if you're having bother with the clutch...assume it'll have it.
Oh and plug your phone in for android auto
