I drive an old shit heap Mini ( really into Minis got about half a dozen of em) and people are always telling me I should spray it. I always reply "Why,so I have to worry about you banging your car door into it"
I also get "You should throw all that junk away and buy a modern car"
I used to swear bucketloads at that but now I just turn and walk as far away as possible.
SOme people will never understand.
