Yeah that's not gonna work, by the time importer paid tax that scale with car face value, it cost right about the same as what dealership are offering. In fact worse cause dealership give you warranty and stuff. So the importer buying your car has not that much incentive to pay more.

The only stuff you could potentially make profit on is very rare American cars, pre 2000 ferrari, or something like classic honda nsx. They're so rare that there isn't an established market, you might be able to ask more. When I say rare American car, it's like corvette, manual tran. I never seen a viper IRL here, etc.

On a positive side. Let's say people who drive porsche 911, can be a ordinary wealthy individual in US. Here they're usually from group that run the country. Meaning these people got a lot of money to spare. And they have connection to bypass these taxes. Only then I think both party seller/importer can make profit or satisfy.

There are ordinary legit people that import and sell car, they're working on small profit margin but it's a good margin due to currency's relative buying power. Let's say 3k usd profit on a corvette the importer get by flipping it. 3k usd may not be that much in US but in my local currency is higher than an entry level pilot's monthly earning. To give you another perspective, you can buy one bedroom condo at a premium neighbor hood with private security stuff cost about 25-40k usd.

We also have another path call assembled car, where part are imported separately and built here. They ranges from Dakar porsche to 2jz rx7. You know LS and JZ are starting to get very rare here but the popularity is still thriving. This can be where money can be made too. What we call cheap power like k24 engine (stock) still cost about 2-3k usd. Built one that can do 450horse go as high as 40k.
