Hi, I am new to this forum today and just bought myself a 52 plate IS200 sport cross from an old boy who has given up driving. Full lexus history and only 80000 miles. My question is; I have a bit of a rattle on the front offside which I think is a drop link arm, I have looked on Ebay and lots of people sell them but only for the saloon. Are the saloon and sportcross drop link arms different and if so where can I get new ones for the sport cross please? Thanks for any help guys. Westy
