Used car prices for IS 250's are definately going up.
I had been looking for a 1 to 2 year old 250 MM in Brechin Slate with Beige leather since March (having gladly got rid of my Mercedes C class Sports Coupe - make sure you have plenty of padding if you buy one - the suspension is very hard).
My local Lexus Dealer tried to find me one through the Dealership network. He found one but the price increased when he tried to buy it. He located another but they told him it was sold - it appeared on the same Lexus dealers site with a £1500 price increase the next day.
About 6 weeks later I located a car myself at Lexus Exeter, on a 57 plate but only covered 700 miles and the full spec which I wanted.
I flew over to Exeter from Belfast and the car was exactly as described, the staff at Lexus Exeter were extremely helpful and I would like to highly recommend this dealership
I drove the car from Exeter to Liverpool the same day - a complete dream - at Liverpool I regretted not having booked a crossing from Stranraer!!!
