Yes, you have very good reason for liking the LOS and your Thai should be a lot better than mine!
I know enough about importing cars to want to discourage you.
Currently Royal Thai Customs are not allowing any S/H vehicle more than 2/3 years old into the country at all. Those they do allow are charged EXTREMELY HIGH rates of duty. Think 2-300% more than Their valuation of the car, they are interested in Your valuation, or the price you actually paid.
They want you to PROVE you have owned and used the vehicle for at least one year before importation. Reg Docs, service records, petrol receipts, the more of this sort of thing you produce, the more they will ask for.
You must make application and receive written permission before exporting the vehicle from it's current location - this process can be lengthy.
And that's just for starters!
Of course, this being Thailand there are several experts who will show you how to get around these niggling details - as a result of which RTC have auctions 3 or 4 times a year which are frequently a full day or more packed with cars where the "experts" slipped up.
The most obvious way is even if you get it past customs and into the country there is No Way you can get a tambian (registration book) for the motor and eventuall you will get picked up - there is no time limit, even if you've had the car here for years it still shouldn't be here and it will be seized.
