Hello all. I'm new here. I've got a nephew (mid-20s) with his heart set on buying a not too old Lexus. I'm a decent shade tree mechanic so I'd like to offer him some advice. Any recommendations as to which models are the most reliable? I presume these are mostly all terrific vehicles but are there any models (or model years) which should be avoided? Any advice you can provide is greatly appreciated. Have a great day and pls drive attentively. Thank you !!
