Hi there, I'm a owner of GS250(2013 F-sport) since 2018.
This is a great car,becoming a rare. Let me highlight the reasons why I chosen this vehicle over others Lexus models at my budget, when I bought mine. Remember, this is my personal opinion only.
I was thinking about IS300h, IS250, GS300h and GS250. 450h was over my budget.
I had to refuse all IS models due to I'm 6ft, and I like to have more room (I can still fit to an IS but getting in/out is easier in GS)
I do like pure V6 engine, simple engine,no turbos, but still enough powerful and sounds nice on higher revs :)
I do prefer traditional auto gear box over CVT. I know, new CVTs are better than before, but I'm a fan of auto-shifting gears.
I do not mind the fuel economy, so I choose pure petrol car over 300h hybrid Lexus.
Service costs are very similar comparing to other models at this age, sometimes are less.
The only cons I found at the moment is the road tax cost but it is law,we can not change it :(
Overall, GS250 is a nice vehicle to drive unless you drive a huge distances.
Do a right choice :)
