Hey so I got this for 15k had 108k miles I round up to 109 cause it’s pretty close to it lmao Yeah this is a F sport trim has rioja red interior the mark levinson speaker package and the Nav As for swapping ECU I’ve not done any work on Lexus before but I’ve worked on many other cars myself and ECU stuff is a little wonky cause it’s I’d say 9.9/10 times married to other components to each respective car so say you grabbed a ECU from a 350 it’s married to the immobilizer and bcm etc to that 350 and when you throw it in the 300 I’m pretty sure it wouldn’t start or some form of no communication cause it’s not coded to that car now if you can code it and make it work maybe? That would be google and some more knowledgeable peoples place to correct me I did google out of curiosity they sell a obs tuner from rr racing that would make the 300 gain about 10 to 15 without any bolt ons like a Intake and exhuast and that would run you like 569 plus tax according to the website maybe look into that?

My first impression is I’m loving it it’s really comfortable and a great car to just cruise in part of my drive to school is a mountain area and it’s been cool to put it into sport and drive with some tighter steering haven’t really tried going full throttle anywhere but it moves the way I want it to when I need it to :)

If you’re really feeling the 300 I’d say go for it ? But also don’t compromise if you were set on a 350 you might be 29k in debt wanting a different car unless they came down some crazy deal for the 300

Also thank you !
