I have a lot of good contacts in U.K. and France. Cheap parts are available in the time it takes the scrapyard to remove them. The real question is is the customer prepared to wait for them to come to UAE?
Barry in whole of sharjah there are only 3 used shops and they basically run a monopoly and these car parts are very expensive if compared to Camry or corolla there was a shop nearby which had 1 sitting and I was called in for diagnosis when scanned it was throwing like grandmother of codes and I told him you have a ground problem or a module fail it needs further checking and he was like OK I will sort it out myself well few days later I heard the car caught fire...
The 206 CC you mean? The convertible? Very popular car in my country and I have a lot of experience with them. Generally, they're good cars if you buy a good one but like anything, there are a lot of dogs out there. The weak points are,
Radius arm bearings in the rear axle. When they fail, the back end can wander. Look at back arches for signs of the tyres rubbing on the inside. Easily repairable if caught in time. Between me and @shadow79 we can repair them, I've done maybe 20-30.
COMMS2000 unit. This is the unit that houses the indicator and wiper stalks. It also houses the airbag and horn clock spring wires and these can break over time. Telltale sign is the airbag light coming on when you are going round corners or parking. Easily replaced if you know what you're doing. £60 for a second hand unit at home so I guess around 300 dhs here.
Roof stops working. 9 times out of 10, it's the control relay in the back or a fuse. Not an expensive fix.
Theyre not bad cars but make sure it has been serviced according to schedule. Timing belt, oil and filter, and if it's automatic most importantly the transmission oil. The autos will only run on clean oil and you generally only get one chance with them. When it's cooked, it's cooked and they need a rebuild.
I was dubious that you said it was 2009 model so I checked. Apparently they built them up to 2016 in GCC. We stopped building and selling them in 2006. Every day is a school day.
I had a 2010 308 1.6 turbo for 1 week and it was fast and smooth but it was factory fitted!
modification is not allowed for daily use road car so please note that if you go for aftermarket modification RTA may not permit renewing the car registration which even harder than losing the warranty as you spent money and time and to continue driving you have to remove it all to stock condition!
so Technician proposal is more safe and applicable and the stock 308 1.6 turbo is about 160 Hp and you can find the same engine in Mini turbo but the variation on the turbo waste gate and inter-cooler brackets.
Even easier still is to just a buy a turbo model straight off the showroom floor. As @Technician rightly says, this type of modification is a real pain in the butt, and I would not advise it uness you have unlimited time, money, and patience.
