I'd get the 350. I was a bit conservative with my 250 but now I know. Although it made me a Lexus fan so now looking forward to my next one, yup an IS350!

Yea i agree with jeff i also have a 6speed and whatever automatic you dive eventually gets boring to just put it in drive and press the gass pedal and the fact that the trans in the is250 is from a truck or whatever people say makes me think its more durable cuz im wrench on the gears

Most transmissions are used in multiple applications, including trucks. I don't see why that is a shortcoming. (R-series and W-series are both considered excellent transmissions, both were used in trucks and cars).
The unconventional output shaft/bearing design may be considered an engineering shortcoming, but even that is questionable considering I've never seen a bearing failure in an RA6x transmission.
The biggest issue is the fact that due to perceived lower loads due to the shaft design, the synchros are supposedly low load-spec'ed. Most issues reported have been related to synchro issues or clutch noise.
The IS250 seems like a relatively light duty application for the RA6x, considering it is used in considerably heavier vehicles with higher engine output (FJ Cruiser).
I find Lexus' choice of shifter setup to be somewhat suspect, as it does not provide a very "direct" feel to the transmission, but I believe that they did it to give a smoother shifter feel, instead of a notchier feel more common on other sportier cars. The F-Sport quickshifter is a good option to change the shifter feel to something it seems more people expect from the car.

I do apologize. this is what i get for not double checking this. i saw one for sale that was labeled as an AWD but when i looked closer at the add it was just a RWD 6speed manual. they just put the title of the advertisement wrong.
your knowledge is unmatched sir

This is a very personal topic, it all depends on the use you plan on giving your IS.. If its daily drive or a second car. But it all comes down to what you are most intrested. If you like stick go for the 250. Two whole diffrent cars, two whole diffrent worlds. Its up to your taste and prefences.

Yeah...Not very many people want to buy an IS250 MT. They sell for quite a bit cheaper than the AT counterparts, so I've learned. Most of the 250 AT I was looking at when I bought my car were about 23k, 22k if the listing was really good. I found my IS250 MT listed at 19.5k. Quite a bit cheaper. I checked the Carfax on it, and it was on dealer lots for about a year.
