Hi scotty:
I will like to buy a is250 and im doing some reach about this car, I recently saw a video of a Toyota service technician he don't recommend this car, because he says has carbon built issues, due to direct inject , what's your opinion about or base on your experience?
in the minute 10:34 he start to explain about bad models to avoid.
He is correct. Those engine tend to build up carbon and it is the nature of engines with GDI only.
Also prepare to buy a lot of front tires, they quickly wear unevenly creating an expense and a safety hazard.
