There is a cop down the street with a pristine '85 Toyota Supra. He also has a late 90's SC400. Never drives either of them. It's a sin. If the engine is still good, that Supra could be worth a bucketload of money. Old japanese sports cars have gone way up in value over the past few years.
My first car was a '99 Subaru Impreza RS coupe. Had it for 15 years till I accidentally put my landlord's lawnmower gas in it. I thought it was just regular gas. The last two years I drove it with no 1st gear because I stripped it doing doughnuts. Great car series which just seemed to get worse and worse with every new model.
Now I drive a 2017 Honda CR-V. It's a great car but... It's not a Nissan Z.
Believe me, the tranny fluid is flushed offten. Though surprisingly little shrappnel is extracted, so at least it seemingly isn't falling apart more than it already has.
I bought the car in this state for $500 a few months ago to teach the GF how to drive stick. I'm not about to try and debug this further so long as the car still gets me from a to b, and at the emd of the day when the tranny finally kicks the bucket it'll be cheaper to just replace the entire tranny from a donor.
When I was in Canada my mazda suv which I bought from a Pakistani gave me the guarantee receipts and what not and since I didn't understand anything he told me that "Car is guarantee, bumper to bumper" so gave him 2k it was a 2009 state of the art model, so after like a year there was problem with the clutch bolts so I went in to the certified mazda mechanics shop thingy, they told me it would take 2 days and I said no I need it today and I waited there until the evening and when the chief cam to me and said "the cost if 6k" and I said "the car has guarantee" he still said the same and I said get me your manager and ofc he went by himself and when he came back "400 dollars" and I said why? He said because mandatory tire inspection, I said I didn't ask for it, so I gave like 200 hundred and left. The next day I went to a local mechanic he had like a shitty shed with tires piled up, I tried explaining the problems and ofc I I didn't know English back then he just popped the trunk looked in, the tires and what not, called his apprentice which is like 15 year old, bough tires, changed them, fixed the engine too. And asked for 150 dollars. I tried thanking him but he said "Learn the fucking language" I gave him a generous tip and thought to myself. Even in a country like Canada there's people like these in the most unexpected places both good and bad. I'm grateful to him.
