Unfortunately, yes, I have.
I rear ended a `ford Focus at about 3 mph at a roundabout.I e=was driving a Mercedes A class. The Merc badge fell ff the grille and one headlight became dislodged. No other apparent damage.It transpired that anAluminium cross member had been bent by transferred energy.
Total cost of repairs £3,000!!!
Focus looked completely undamaged , but again the cross member behind the bumper was bent. I don't know the cost of her repair was but her total claim was £,300 as the *********** made a false claim for whiplash.
Get your Jazz to your dealer and get it checked out.
The problem is, in modern cars, that the plastic is so flexible it pops back into shape disguising damage behind it.
I do hope you got the other drivers details??!!
God luck.
