Well the car market in SL is actually full of BS. Well diesel converted Europeans are cheap due to the engine conversion reason, no resale value but only a one who is desperate to call himself owning a prestige automobile will buy, or you can buy and replace the original engine and up the market price
Furthermore you can go for a Corolla 110 if you can up your margin by 150,000. Nissan FB/SB 14 is also good.
Diahatsu Mira/Daihatsu Coure is also good, but a compact car.
