As above, electrics. I've had a few Clio Sports, nice cars but most are riddled with electrical faults. My old Clio spent 3 months in a specialist Renault garage and it still wasn't fixed properly. I ended up loosing thousands and selling it as repairs.
The common with the Clios is the electrical warning light causing the car to go into limp mode intermittantly.
As a fellow Scoobynetter I'd say look for something else, if thats not an option be very careful and ensure a long test drive!
