Panel gaps came out perfect
Second one of these I have bought, this time for the Q7 4M. The bodyshop test-fitted it before paint and needed almost no adjustment. The swage lines and body contours follow the original exactly. Result is it has been on a year now with no sign of corrosion at the seams. Delivery was quick too.

Primed and ready to paint
Went on my Q5 8R 1.4 TFSI at 155k miles. I lined it up against the door shut and the gap fell straight in. All the mounting tabs and clip locations are present and in the right place. Result is it has been on a year now with no sign of corrosion at the seams.

Saved a fortune on the repair
Fitted to my 2022 Q5 FY. All the mounting tabs and clip locations are present and in the right place. It clipped into the factory mounting points without drilling anything. Result is the paint match came out perfectly with no ripple in the reflection. No complaints at all.

Lined up first time
Ordered this for my Q3 8U after the original gave up at 80k. It clipped into the factory mounting points without drilling anything. All the mounting tabs and clip locations are present and in the right place. Result is the finished repair cost a fraction of a dealer panel.
