Ive always had solid built cars until and always used my hand to assist in closing the bonnet until I bought my brand new Reno 182 back in the day. I literally picked up the car from Southampton and drove it back down to Swanage and thought I would have a noesy at the engine, after I had finished I closed the bonnet how I normally do without a second thought. End result was a hand print dent on the bonnet, wasnt sure whether to laugh or cry
So now I always drop the bonnet from about a 1ft lol
