Most of the time O2 CELs are disabled by putting the front O2 sensor in a constant state of "not ready" that would cause a car to fail in a state like mine (IL) that requires all emissions equipment to display readiness when scanned from the OBDII port.

In IL, in the counties that smog, a CEL is also an automatic fail. Actually, if your readiness codes have been reset, it's also a fail.

Yeah, I live in Lake Co. IL. They actually did a visual inspection on one of my cars with a cat-back, lol.

That's actually the original reason why I asked the question. I lived in the Silicon Valley for a year, and vaguely remembered that from when I had to register my car.

That Webbo? lol

Apparently, it's legal gray area. If it's disclosed, then no problem for the seller. Some states, however, allow a buyer to cancel a sale if the car cannot be legally registered due to not possessing all required emissions equipment.

That's what I thought. But, you know... EPA - #lawsaboutallthethings

Amen, haha.

Is it legal to sell a car sans cats, though?

goddamn right it is

I did this all the time when I sold cars. Dealerships are all closed on Sundays in IL. I’d flip a customer a set of keys Saturday afternoon and tell them to come see me before 9PM Monday.

No. They don't sell cars. See: Lotus sales numbers for, uh... Ever.

That’s a lie.

I had a deposit down on a MKIV R32, but wanted to check out an Evo VIII before fully committing. I walked into the dealership where I had also bought my 2G Eclipse, told the salesperson I wanted to drive an Evo before committing to the other $31k car I already had a deposit on.

For a car built in 2015, the answer is the base model Corolla.

Good man. I was 23 and even dumber than I am today.

A-fucking-men

It seems like he didn’t get their blessing prior, pissing everyone off. Plus, ze Germans go about the business in an entirely different way.

Sell unobtanium for the sake of a woman, that is.
