Most "temperature tolerant" basses?

You missed the point. The OP wanted to take a bass to work and leave it in his car so he could practice in the car at lunch. Put your soapbox away. Basses are made of wood and steel. They are not artifacts. They are tools. I leave me tools in my truck all the time. And they're fine. Lighten up.

Not a soapbox just don't understand why leaving it in the car is better 24/7 than taking it to and from each time. I have no problem leaving speakers, amps, cables,etc in cars. The issue I see is leaving an instrument that relies on consistent tension to maintain tuning and intonation in an environment such as that. He will spend more time tuning and fixing the neck than practicing, and if not the practice won't be worth much otherwise.

I've had 3 modulus basses and while the necks sound great, and are fantastic for changes in humidity... I found them to be very sensitive to changes in temperature. For me, this meant tuning my bass constantly due to the neck "warming up" and "cooling down".

I only play wood necks these days, because I got tired of tuning so often... seriously.

Weird, I have exactly the opposite experience with my Modulus: For the past ~8 or 9 years I've kept it in a rehearsal studio that has its heat and/or AC shut off from 2:00AM to 8:00AM every day, year-round, so the bass often experiences >20 degree temperature swings routinely.

If I have to tune it every two months, that's a lot. It's ridiculously stable.
