Insurance is kinda high and plates will be to! lexus suvs are nice a used one would be under the 30k mark. 2007 -2008 lexus gx suv is around 27k. 2007-2008 lexus rx is around 20k to 27k! it all dpends on what you are looking for you can get a newer one with good miles for under 30k Good Luck!!
Mark, it really depends on your age. Because I do not know your age, it is impossible for me to estimate, but it is safe to say your insurance will be low if you are over 25. My fiancee has a 2011 Lexus RX, but she is under her parents, so the rate for her is quite low. She never got speeding tickets and she also never got into accidents before, so that is one of the main reasons why her rate is low. I'll have to ask my fiancee, but I highly doubt she knows it because she doesn't pay for her insurance.
Which Lexus SUV are you thinking of buying next year? What do you think of the sedans? My younger brother has 2011 Lexus IS with Fuji-sport suspension (the ones from IS-F) and it is much better than just normal Lexus ISs.
