I have also just completed 2 years of my 2010 IS250 Cabrio ownership. Apart from annual servicing & tyres, I have had to replace the battery & one tyre pressure monitor sensor. I have done about 6k miles in those 2 years, only using it for longish trips (minimum 50 miles - I have a Smart car for local journeys). The car has just completed 38,500 miles. I've found it to be very comfortable & a great car to drive. Unfortunately, I'm finding it difficult to justify (to my wife!) ownership, bearing in mind the cost of Road Tax & insurance whilst doing such minimal mileage so under increasing pressure to sell unfortunately. Pleasantly surprised that a 14 year old car has been so reliable.
