Here is my update on the parts that I received at the fractions of the OEM price.
I got all the parts within 15 days from China (even tho it's the festive season)
I paid £151.68 all parts (Inc P&P) + £28.95 for Import VAT and Clearance fees.
The chrome mirror covers I got is 'stick' on, it was my best interest to keep the stock cover as it is and also minimise the cost. £19.88
The two small chrome parts stick just under the rear roof spoiler. £8.95
Boot spoiler also 'stick' on but I got the carbon fiber style. £43.36
Front and rear bumper styling in 'silver' comes with all the screws and English instructions. (Although I never seen what the OEM parts or Fixing instructions looks like). But it looks like a real deal. £79.49
Apart from mirror covers rest fits in places as it should be. Mirror cover does stick out a bit but then again it's the cover so I guess it would stick out a bit. I have no issue with that so far.
So far Aliexp** has been advantage for me. (Please note that my intention here is not to advertise the marketplace). Just sharing my experience.
I will update you guys once all has been fitted into the car.
