I loved my CTR just the same. I lived in a terraced house on a main road and I had to keep it one street away behind the house outside somebody else's houses. The town is a hole, lots of chavs and idiots plus it was parked on the main routes home from the cluster of pubs just down the road. Not once was it touched in 3 years despite it being parked half on the curb half on the narrow road.
There may have been the odd mark on there, but nothing obvious that bothered me that I could trace to any particular event. At the end of the day it's a car, it was my pride and joy and I loved driving it every day. I'd sooner get stone chips, scratches and lose a bit of value than compromise my passion for cars for "what ifs".
I later had had my MX5 in the same place for a few months, not a problem. It's not a stress at all. Only if things do start to happen should you might think about maybe changing things, but even then I'd go down the CCTV and other security routes before letting go, if you really love your cars that much.
The only reason I got rid of my CTR was because my ex wanted to go to uni and we would have been stuck money wise. That was an easy decision to make, family comes first so to speak, but in hindsight... ****!
