I know how you feel mate. Ive taken so much care of my car. Washed it every week, interior never had 1 spec of dust on it. Everyone was surprised how clean it was. Then all of a sudden came a taxi driver that demolished my rear end. It got fixed, but since then i have washed it once (happened in January). Also i have had minor things that shit me like little rust specs were a rock has hit it and chipped the paint then it rusts.
Ive gotten so annoyed with it so i decided to go all out to MAKE me pay more attention to it lol. Its at the panel shop as we speak getting a full bodykit and a custom respray job. Hope that cures me not taking care of it lol, turning it into a show car
