You can't handle the U mate, driving a GQ has made you soft!! Lol. I say invest in a donkey, all you need to do is feed it and it will take you to work and up any track easier then the Q too hahahaha
You could just ride a push bike lol but seriously WTF!! Tell NRMA its not your problem and you should be entitled to the car coz if the job was done right in the first place you wouldn't be having the conversation with them now, so either they or the panel beater should supply you with a courtesy car. OR you could just try and squeeze 4 g's out of them and get a full respray for 2 lol i would try and get a pay out and get it sprayed, but my cousin is a spray painter so i only pay materials and the oven and feed him pizza and slurpees haha
