I have sold quite a few cars haha and I am always very honest when advertising my cars and provide as much info as possible as it only helps me sell the car really.
People writing that their car is 'mint' for it to only be full of rust and less straight than elton john only affects the sale negatively for them.
Never really had any problems selling any of my cars, have sold all of them pretty simply.
I sold my old KE70 I had a few years ago to a 16 yo guy and he was okay during the purchase, although he did end up writing that off within a few months lol
When I sold my old yellow 3TC KE30 late last year it had something wack in the rear end which I hadn't had time to check out but suspected to be axles (I had spares anyway, as the 3T had massive torque and split axles lulz).
The interested parties came from way down south (about 1 1/2 hours away), had a look at and were pleased, a deal was made and they wanted to drive it home. I explained to them that the car vibrates pretty badly over 35km/h and I myself wouldnt be keen on driving such a car over an hour and a half drive in the condition it was, I even took them for a drive to demonstrate how the car behaved. I was quite willing to have a look at it the following day and fix whatever was needed, but they insisted on driving it home slowly.
Now I will mention that the whole time one of the friends (a young guy about 17 years old), was telling me how he has had a few "fully sik ke70's he had bought for $200, locked the diff, cut the springs and drifted yo". I was getting pretty sick of his multiple dodgy tales of thrashing POS cars. From what I can remember he drove the car home.
I got a phonecall the next day telling me that on the way home on some freeway down south, whilst driving one rear wheel had fallen off and the wheel bearings/axles/complete diff were now 100% broken. that weekend I gave them some spare axles and told them to give a mate a call as he had a cheap diff for sale. afaik he never heard from them, and fuck knows how this dickhead drove it home given his record
a few months ago the young guy friend was on a forum saying something about thrashing his old KE70 while on defect. I made a comment about how "fully sick" he must feel now, and he then threatened me on how I could've had a very expensive courtcase on my hands due to the breakages in the car. I just LOL'd
Thats my story
