I was forever falling out with mine, had it 4 years and probably decided to sell it about 4 times but then quickly retracted. The final time I decided to sell it, I priced it well to ensure it went quick before I changed my mind. Im currently supraless and to be honest, I'm finding it a bit of a relief.
The car became less of a possession and more of an obsession; wouldn't park it in small or busy car parks, wouldn't wash it without foam pre wash, oil changes every 4 months or I wouldn't drive it, I wanted to replace everything on the car too. Sold up, bought a superbike and am enjoying the cheap thrills.
I will own a supra again because i think theyre the balls; but in my opinion, unless the car is just a weekend toy, they can be a bit consuming and you will need a break from them to get the love back
