When did the second gen R129 start?

Hi all, I have been looking for the right R129 for awhile now and as a result I've come across many cars. One that is currently on the market puzzles me as it appears to have a mix of gen 1 and gen 2. The car in question is built in March 96, and has all the hall mark of gen 2 (exterior, steering wheel, seats, 5 speed etc) except for:

1. Older style HVAC control units
2. Bornite in colour (which I believe is only for the gen 1 cars)

Can someone confirm if this has the wiring loom fix from the factory? And would the vin provide the answer as to whether this is gen 1 or gen 2 car?

Thanking in advanced!

HVAC control was changed in Jul 1996. Seat design was changed in the 1st facelift Sep 1995. Bornit was available up to 1996. The only way to confirm whether the engine harnesses have been fixed is to have a look on them (or manufacturing dates on the harnesses). Engines M119 and M120 with LH Jetronic SFI are especially prone to crumbling wire insulation. VIN may help or not. IMO your details point to facelift 1996 model.

Thank you. That gives me more confidence. This is the car in question. I'm super keen on it.

So would a 99+ car be a Gen 3?

yes that is correct. In fact I think the gen 3 started build in late 98? Not sure.

All cars built from Sep onwards are designated as following year models.
This applies to many manufacturers
