Can you buy a car or bike in Thailand with a DTV visa?

Yes, Certificate of residency issued a week after arriving on a DTV and registered a car a few days later.

Even a house or a condo, but not the land.

Buy what you like hon.

You buy with cash 😂

No, the seller wants to see money and the registration office wants to see a residents certificate which you will get with any permission to stay or visa which has still 30 days before expiry.

You can if you are paying in cash and don't need a loan. If you need a loan then that's more complicated, you probably can't.

Nah best to use cash

Yes, but you must have documents from the Immigration Bureau.

I’ve bought 3 cars in visa exempt

You need

— Work Permit OR Certificate of Residence

— Thai Driver Licenses

— Money, but you can pay cash

You don't need any visa to buy anything in Thailand.

Yes. You can buy a car with a dtv. Did you mean can you get a loan to buy a new car and pay if off monthly?

You don't need any kind of visa to buy a vehicle. But if you want to register it in your name you need a "certificate of residence" from the Immigration. And to get this you need to do a 90 day report first (officially). Since you can stay longer than 90 consecutive days with a DTV the answer is yes, you can. If your local Immigration has different requirements and you face any problems you can use an agent as well.
