I too was attached to my car, My first car was a civic EG. Bought the car blindly, impatiently, and had no knowledge about cars at the time,
and i was by myself (yes i know, stupid. I was young and dumb). Paid the dude the money.
Turned out from my uncle i bought a lemon... lol. Anyways, car had lots of problems, replace engine, drums, master cylinder, dizzy, re-tune dual carby, etc etc.
Then it behaved properly after all my $$$ said goodbye to my wallet. Then the cosmetic mods came in, bit by bit, i fell more attached to it than the frustrated earlier me.
Vowed that ill never sell the car, that if i were to buy another car, atleast keep it for track use.
Then.. one day, the engine started getting hiccups up every time stopped at the lights, I said to myself "what now?!, fuck this shit! i'm selling u" So, Had her put up for sale. And sold it.
So, the advice i'm pointing out is, time, thinking, and future problems in the car will assist ur decision on what will be very hard to sell at the time, to "i'm selling u, bitch! we're breaking up".. Funny thing was, spotted my old EG last couple months, talked to the owner, said it had the engine replaced again.
I did this with the evo, replaced it with a "family oriented" SUV, because It was what I thought I wanted / needed. I regret the selling the car each and everyday, If I had the chance to do it all over again I wouldnt even think about selling it.
