Rule out the GM 6 cylinder engines. They had problems with the intake gasket (many failed multiple times over the life of only one engine) and some had problems with plastic parts used for coolant, and most have problems with EGR passages and valve, and the EVAP system valves once they get to around 115 K miles. I would rule them out of any engine that I would have chosen to have in a vehicle from the start and planning to keep it for 200 K miles or more if I knew then what I know now about them.
what is the best v6 ever made?

I also thought of the old 225 slant 6. Those were bullet proof reliable engines, but only the last couple of years had hydraulic lifters that did not require being adjusted often. My 1976 Volare with solid lifters required adjusting the valves every 10 K miles. They were easy to do, but they were something that you had to keep on top of. You did have to keep a spare ballast resistor in the vehicle because you never knew when it would burn out, but you could swap that out in less than 10 minutes, and they rarely failed and usually only on start-up.
I once heard that Chrysler had to stop producing the 225 because it could not be made to meet the increased emissions requirements.
Not a v6 however the AMC/Jeep 4.2 I6 was beyond reliable and stout motor. Our Jeep CJ7 and AMC Eagle growing up drove till near 300k without touching the motor. Dad was a traveling salesman with New England and NY state as territory driving.
Weird motor with 100 HP at 3200 RPM and decent 200 ftlbs torque at 1200 rpm.

If that's the only thing wrong with the vehicle.....?? The repair costs aren't any greater than a Timing Belt job on a Honda J-series or a Toyota MZ-series.
I'm a big fan of the Buick 3.8L V6. I will always go for an Inline 6 over a V6. With some mods you can get some crazy power out of an I6 motor. There are number of guys over on YT that have turboed 292 Chevy's and 300ci Fords and were pushing over 400 HP.

One of the people on the JV6 team retired to the midwest and wrote this post detailing its history.

um... none?
I have yet to hear a V6 that sounds good. So utilitarian but sound like unfunny farts. I like inline 6s, but that's a different category.

I was going to reply with the same. I love old school Toyota 4x4 and always search the 22r due to the 3.0 head issues.
Favorite: Alfa Romeo 3.0 sohc 2 valve V6. Not the DOHC 4 valve version. Certainly this sohc engine is NOT reliable tho with its wet liner iron barrels + its oil-fed cam-belt de-tensioner. The sound for some reason is fantastic. CAN be made to be somewhat more reliable though...

Modded Turbo 3.8L Buick's were making over 400HP in the late eighties.
it got banned from the IHRA real quick
This is BITOG, where 20 year old Corolla’s/Camry’s and Crown Vic’s are the absolute epitome of automotive engineering. Anything else is considered by most as gas guzzling, inefficient wastes of metal and dinosaur squeezings.
The v6 in the Camaro sounds pretty good, my boss has an RX-8 with one swapped in and a custom exhaust... sounds like a VR6.
Detroit Diesel 6V-71.
I like the GM 4.3 for its service in the marine ands industrial environment.
Toyota's 2GR-FE has been around forever, and served in many different vehicles. Great engine. (sounds amazing to in the Lotus Evora GT)
I am also going to throw the Pentastar in with this group. Sure, it has its teething problems, but it really has evolved into a good engine. It too does its duty in a WIDE variety of automobiles.
I also have a lot of love for the L67/L32 3800 supercharged engines.

Toyota 3.5 2GR-FE
Excellent reliability, power and fuel economy.
GM 3.8
Aside from the intake failures from the EGR tube cracking them, leaking coolant inside. Or the coolant bypass tube...these were solid engines with reliability, power and decent fuel economy. A lot different than their little brother, the 3.4 V6 GM junk.
