Hi all. I’m vIewing 3 x 2015 WRX STI. Taking mechanic with me but anything we should be looking out for in particular engine-wise? Will knuckle down and read through the forums as soon as I get chance. Thanks in advance for any advice. Gary

Check for cam belt change if needed.

Make sure it has antifreeze in the rad.

Start car from COLD and check for smoke, always turn up early so they cant start the car before you get there

Wotcha and welcome - as above, check also for signs of emulsification in coolant - before you get the engine warm 😉
