New to Lexus, have recently ordered UX 250h PREMIUM PACK WITH 18" WHEELS, TAHARA, BSM & RCTA, due end of July 2023. Coming from a Mazda CX-5 2.2D. Only downside I can see is smaller boot which I think I can just about live with, we are a retired couple with rough collie dog and occasional trips with grandkids….My contingency plan should I need extra space is roof bars and box (will probably not put dog and grandkids in box…), any recommendations?TIA
