I paid £800 for my W reg st24 with only 77k on the clock full service history about 14 months ago, i upgraded alot of parts to st200 items engine wise and had the ecu remapped its now runing a healthy 212bhp soon to be more with the help of MSD style headers and a different chip. As mentioned before a good service history is a must with these cars.
2k will get you a good st200 with service history
