Lexus is one of the best, if not the best IMO. I tried a Jag, BMW, Mercedes, Acura but Lexus beat ’em all. The exterior styling of some models doesn’t come up to scratch with its European counter-parts, but the interiors do. The Sat Nav isn’t as great as the Acuras, and the IS 250 models drag a bit around town but get ’em on the freeway and they purr. The Jag is basically a Ford, and Beemer and Merc interiors at the low end reflect conservative German styling i.e. little to no flare. Performance wise I’d think they are all much of a muchness, but gas mileage should be a biggy these days, and may be reflected in future resale values. Just my tuppence worth.
