I was washing my dad's red GP and forgot to engage handbrakes. It rolled back on the ramp and banged against the rear right wheel arch of my white Punto. Moreover the front tyre rolled over my toe that is slightly swollen and bruised with a cut. White Punto traveled 1 feet sideways and has dents all over rear right wheelarch. Red Punto: has a misaligned bumper, both number plate lights not working, dent below the boot lock keyhole area besides scratches on dent. small dent and 3cm scratch of driver side door (it stuck against the gate while I attempted to engage handbrake. Everything happened in a flash. Can not explain how sad I am to look at our two cars and both getting dented like this due to my negligence. Already I have too much stress of studies and now this. 2 weeks back a dog came in front of my car and the lower front grill is already out. Hoping that the boot dent can be fixed in that tricky area.
