Being a former Lexus and Toyota technician I would have to say the 1st and 2nd gen LS models. With that being said though, my 01 RX has 351K on it with only 1 small repair being done. This thing just will not stop going.

 

More reliable than a LX450?

 

Have you seen an LX450 with 351k?
This is exactly what makes me like Toyota and Lexus so much!

 

Those are pretty bullet as well.

 

Here is the 350K shot.

 

surprised the ODO hasn't broken yet
Bet it can make it to 400k.

 

I had a lx470, not as reliable as LS. Antenna broke @ 50k, starter failed at 60k, airsuspension had issue too.

 

My 1999 Lexus GS300 has been pretty good...

 

Outside of Lexus I'd had an '82 Maxima that was at 280K when the ECU went south. Between me and pops, neither of us have hit 300K. Whatever we've had is pasture material in the 250-280K range. I'd like to see our LS hit 300K. Along that path, there will be some heavy repairs to consider and that becomes a big obstacle as one repair leads to another once the process begins.

 

I was going to say the early RX's were the most UN-reliable Lexus, but if one can reach as high as 300k, that's pretty good!

 

The early RX's are not unreliable, in fact my RX is probably the most reliable car I've owned, and that's saying something. (look at my signature, you'll see what I mean). My uncle's 99' RX has 380k miles (original engine & tranny), it still runs like new, and is also extremely reliable.

 

We should make Lexus the car with the highest miles in the world instead of that Volvo with 2,900,000 miles!
LS could do that better than any other...

 

I'd have to say the first three generations of the LS, the ES250, and the SC400 are the most reliable Lexus as far as the engine goes.

With the SC's, the engines last forever but all of the fancy electronics don't.

 

I've seen an SC with 327k for sale for $1500 before!!!!

 

Considering that i just spent the day 200 miles frim home repairing my car.....id say NOT the 92 LS.
