Been thinking about selling mine a few times, and even more so now I have a gorgeous optioned up BRZ to drive around.
Two things that have stopped me thus far is I feel the car owes me more fun than what I've currently had in it, especially with the amount of hours I've poured into it fixing it up. I'm so close yet so far since there's a few more grand needing to be invested getting the transmission rebuilt, and eventually the original engine too. For now the replacement engine it has is fine though.
The other one is my daughter loves it and even before I bought the BRZ she would tell me she likes my little blue car, which is about as far as her vocabulary goes in saying she wants me to take her for a drive in it.
Aim is once shes 4 years old and can wear a lap sash belt with a booster seat, I'll fulfill that wish. Still have over a year to get there luckily.
At that point it'll be very close to historic rego time, so it'll only be a case of making sure I have space for it.
