STAY AWAY!! They don't care about their customers after the sale

I purchased a 2nd hand vehicle from the owner of this company in August 2024. This was supposed to be my 18 year old's 1st vehicle. Yes, it's not new, and it was not over priced. However, every single concern raised by me about faults on the vehicle, or probable obstacles to register, etc, was waved away and promises were made that it would be sorted out. The first battle started with COR and registration. The vehicle was lowered by the previous owner, and I asked the owner of the mentioned so-called car dealership, if it would pass COR being lowered. He answered, it would, and if not, he knew someone who would be able to lift the suspension again, at a special price. This person says he doesn't stock the suspension for this specific vehicle and wants nothing further to do with this issue. I contacted the owner, who said he'd find someone to do the work. He is now not even answering messages and ignoring me completely. When it came to registering the vehicle, I did not have the correct documents to do so, and was shouted at by the owner who sold me the vehicle. Not only did he shout at me, but also the woman at the registration offices, telling her she didn't know what she was doing and how stupid she is for not knowing. It took a connection of him over a week to register the vehicle - something they deal with on a daily basis? Also, they couldn't register in my daughter's name, cause my affidavit that was handed in as proof of residence, everywhere else accepted as she is a scholarship, wasn't legal??? The rear door shock of the vehicle is non-operational, and when I mentioned that to him, he said he'd find a replacement part for me and even install it. I'm still waiting. He swore the engine of the vehicle has never been opened, yet, mechanics tell me otherwise as wrong bolts are installed in sections of the engine, some are non-existent. I am now sitting with a vehicle that is costing me way over budget price, to get oil leaks, broken switches, suspension, lights and other electrical components and door shocks, fixed. Please be super careful when buying from this car dealership as they lie about the condition of the vehicle as well as after sales promises that are not kept. I am super disappointed that human beings like these walk our earth and they don't even worry about their company name, and obviously also not about their family name, AND DEFINITELY NOT ABOUT THE STRANDED CUSTOMERS. Promises made before payment, and nothing came from it!!
