Turbo needed rebuilding after 60000 Km. ($2000AU to fix)
Seats were worn easily.
Radiator overheated and leaked. @ 61340km.
Door did not seal properly and was difficult to shut. This cost $1500 to replace the door and re-fit electrics.
Leaver for folding seat forward snapped off on passenger side.
Rust in boot lining, major problem is getting rid of it.
Tire in front drivers side kept wearing out and had to be replaced regularly.
Failure to start on most cold mornings. Had to borrow my brother's fiat X/19 to drive to work (30km drive around tight bends)
Fuel injector busted and needed to be replaced (replaced with a high flow injector)
Head gasket blew at 65780Km. this was the last straw for me. This car just had to go.
This car is quick, but what people say about these cars out running everything on the road is bollocs. I tried racing/dragging Porsche's (old ones at that), a Saab 9000 Carlsson, some slightly modified performance Citroens (BX 16v and a CX turbo), Subarus, a Lotus Elise, a few Ford Falcon XR6 non turbo and turbo variants, the list goes on, this car just could not get going fast enough to match all the guff that people said about it. I feel that my old Citroen BX 16 valve could get going quicker and that was a non turbo vehicle.
13-litres per 100km fuel consumption if driven hard.
All the nonsense that people say about it handling well is ridicules. The Citroen could out pace the Skyline around the twistys easily.
I read the magazines about how you can tune these cars and make them go faster than a Ferrari. Well if you want to kill the engine in six months then yes you can go faster than a Ferrari, but it will pay you back with frequent breakdowns.
Police attention is massive. I would get pulled over twice a week at the least and on one trip home from work I got pulled over 4 times and by the same officer two times in one night. These cars are cop magnets. This never happened in the Citroen.
The mechanical problems were endless and when the radiator went I just had to sell the damn thing. A lot of mornings it failed to start completely and I had to borrow my brother's Fiat X/19 which would also kill it around the corners and it was built in 1982. Citroen's have a reputation of spending more time at the mechanic than on the road, but I found it extremely reliable in comparison with the Nissan which lived up to the "don't buy imports as they brake down" reputation.
The seats are uncomfortable, but I can't judge this too harshly because he Citroen was the best long distance traveler I have ever driven and was extremely comfortable.
