Any good? What price is acceptable if 2021 made now?

35-45k should be acceptable

Where did you see the listing ? Is there any 2.0 NA unit ? That should be more reliable as the 1.6T is using dry clutch DCT.

my friend dad's car . he wanted to sell it . looks good and performs really well. too bad it is discontinued (?)

oof , dry clutch DCT.

Ya as I read most if not all 7 speed DCT are dry clutch. 8 speed box is wet clutch, like the one fitted in Sorento.

Elantra Sport same dry clutch 7 speed DCT, 8 years and counting. No issue.

Most important is the how much torque a transmission is designed for. This DCT is designed for 320Nm, so it has a lot of margin for the 1.6T.

The rule applies for any transmission AT, DCT, CVT, MT. Always refer to the torque limit vs the engine output.

Did you buy the car?
