Sorry to hear about what happened to you mate, hope you get your car soon, no worries I live in north london and I drive between north and east I will keep an eye for blue lexus around my area, I got bad habbit at Staring at other IS 200’s
one more thing is there any sign that will distinguish your car from the rest , I got funny feeling that the first thing that they will do is to replace the number plates, is there any signs on your car like exterior after market kit or anything? photo of your car will be nice.
