theres good and bad in all cars but the 170 if well maintained can be a good car, dont just buy on price check history and look for main things like a good clutch as a new one will cost you £800 ish, rust and engine management lights and most of all drive it, spec varies as there are 3 specs, base = black headlights & half leather seats, then you have the climate pack which is xenon headlights and climate control then the climate & comfort pack edition which is the daddy, full leather recaros with xenons and sub woofer and if you hit one with all that plus options of sunroof and rear parking sensors then you have peaked into top spec
