Mine has a ripple in the roof because some plonker sat on my roof!! silly twat - i could be that you know...

My corsa has a few ripples in the roof

I have a corsa sport but i don't have any ripples in the roof and it the first i've heard of.......... so i doubt it.

All looks OK could this be another problem like the earlier corsas had with cracking B pillars and to much movent up top

check the panels for alignment. check for fresh paint where panels ahve been bolted down. Check for new bolts that have not been sprayed over (cause they have been replaced) check for any sort of panel rubbing e.g when opeing doors. look for welding underneath carpets that's not meant to be there. check one side of the car to the other (left wing with right wing etc) should be the same

I recently bought a corsa sport but on getting it home and having it a few weeks there is a ripple in the roof pannel near the front.
Its mainy in the paint work and can only been seen when the sun is shining on it.
Could this be evidence that the car was in a crash or can it just happen I will try and get some pics

Also is there any thing I can look for to see if the car has been repaired after a crash
