can not find anything about 4 doors being a problem. A passenger car (to a 1 million baht limit) can be claimed as an expense through depreciation. I also found that the 7% VAT can not be claimed as a VAT credit, but the VAT is part of the asset value and hence claimed through depreciation. I know our Hilux is currently personally owned, but we wish to buy I car in the future, so I need to understand this correctly
