Very interested to see how you get on because if you are successful, mine being a 2003 Celsior/LS430 with the same engine I should be in the same position.

Just received confirmation of ULEZ exemption (within 2 working days) from TFL for my (late 2000) LS430.  Hooray! 

I believe all 2000-2006 (UK) LS430 are ULEZ/EURO 4 compliant. 

The CoC is worth getting if you don't already have it (even if at £75).

For anyone that sees this in the future - I contacted the Lexus Certificate of Conformity department to check if my late 2000 registered model LS430 was in principle Euro 4 compliant before I paid them for a certificate. 

They have just got back to me, and stated that based on my VIN, my car is not Euro 4 - it was Euro 3 compliant when built. 

To quote the email from Lexus:

So it looks like many (most?) LS430 are Euro 4 compliant (and therefore ULEZ exempt), but some of the early ones like mine are not.

Shame.

I also have a late 2000 LS430 and live within the CC and ULE zones.

My late 2000 LS430 came up as NOT exempt from ULEZ, despite 2001 onwards LS430s are ULEZ exempt. I was gutted and most reluctant to make such car redundant due to some stupid charge, I started to google. 

Although built in the era of EURO 3, the LS430 was an early adopter (TFL term) and exceeds EURO 4 standards (even EURO 5 compliant on CO, HC and NOx, although the CoC did not show PM values):

Euro 4 emission limits (petrol)                                    LS430

CO –      1.0 g/km                                                              0.230 g/km

HC –       0.10 g/km                                                           0.040 g/km

NOx –    0.08 g/km                                                           0.020 g/km

PM –      N/A for petrol

As all the LS430 had the same 3UZ-FE engine, and since the MoT emission requirement for 2000-2006 LS430s were identical, I wondered if there was any difference in emission pre/post 2001.

I researched and contacted Lexus, they were not able to confirm/deny in email communications any difference between pre and post 2001 LS430s. 

Initially Lexus emailed an EURO Emission Letter stating the obvious, EURO 3 compliant (as the car was built under this regime).

I went on to press for the detailed emission figures, Lexus then sent me a duplicate Certificate of Conformity, which confirmed 2000 LS430 has the above emission figures, same as post 2001 LS.

(without asking me for the £75, but probably because I bought my LS430 from Lexus dealer and I was not given the CoC at the time).

I just made an application to TFL with the CoC and V5, will see if they grant the ULEZ exemption.
