Thanks, I am enjoying it. Not sure how long the 20mpg will be fun, but so far, so good.
I intentionally bought cheap as I have always wanted to try an LS ever since they were first introduced, but I wanted a car I could walk away from should a big repair bill hit the mat. I think the filthy condition of the car was the main reason for the low price, but a weekend spent cleaning it has turned up a gem. I finally had a look through the service receipts a couple days ago and it is shocking how much money the first owner spent on the car.
