Thanks all for your feedback, I think I am still going to look for an is300h (despite some people’s negativity about it), I’m not after performance I am just after better fuel economy. I have seen that there are lots of these for sale with 90k+ miles on them, should I be weary about buying a 300h with this sort of mileage on it?
Regarding the power of the vehicles I think that they are partially under powered compared to other vehicle ie bmw/Audi but the variant of the Lexus models I feel doesn’t mean that they compare to that power ratio (ie 250 as these cars are based on the engine size hence the is250-2.5 litre, is200-2 litre, gen 1 is300-3litre, unfortunately Lexus cars are heavy vehicles so give a poor power to weight ratio hence the reason they are slower than their competitors, but I guess they are well equipped with leather/sound deadening which compromises this problem.
