afaik no. My gf recently went to do her TR visa extension but they were going to fine her something like 3k baht for not having done her TM.30 properly. They told her once she paid the fine and got the TM.30 she could finish the extension the same day. She ended up doing a border run instead to restart the clock with a clean slate.
Can’t do 90 day report without a TM.30 - it’s very important to ask about TM.30 when booking long-term accommodation here. You can file the TM.30 yourself at immigration though if you have a copy of the owner’s passport and ownership docs, but expect a fine if you waited too long.
I used a loan from my bank in the US to buy mine. I just had to put down a deposit to hold the vehicle until the funds were available to complete the purchase.
