Agreed as to the credit due Lexus, but they're not acquiescing to my assertion that the oil use and misfiring are related & they're not doing anything about it for me but state that "1 quart per 1,700 mi. is w/in factory parameters."
No car manufacturer today should tolerate that kind of oil consumption, let alone state to their customer that it's how the vehicle was designed and what the manual allows - demonstrates some engineering issues with Toyota ... this from a guy who's been to the Rainbow Bridge Toyota facility in Tokyo three times, BC I'm a "Toyota guy." I am a Land Cruiser die-hard and I think the Supra is one of the best overall cars ever made ... I think Toyota is a good company, but I've owned 4 Accords, two Civics, one S2000, multiple Honda motorcycles and countless small engine-Hondas .... NONE of them have ever caused me ANY issues, let alone one of this magnitude. From my limited experience, next time I go for a luxury car, it's going to be an Acura.
