kirban 2 cents worth
My background having bought over 300 plus Turbo Regals most of which I have trailered back to PA I can offer you some serious insight.
I am now on my second car trailer and gone through 3 sets of tires on the first trailer.
First, by law trailers have to have 4 wheel brakes. You want to get the lightest trailer available and one that the doors open when car is on the trailer. Look for a trailer that weights empty around 1,300 t 1,400 lbs.
Buicks weigh about 3,400 in round numbers. So right away you got a total of almost 5,000 pounds swaying behind your tow vehicle.
On a smooth flat road with no bridges no wind and no 80,000 lb tractor trailers passing you, you may never have a problem with your roadmaster or any othe rcomparable tow car.
However, it is by far a risky choice. It also may prove to be an excuse for your insurance company should you be involved in an accident to not cover you.
Your mechanic is correct trans heat up shocks are weak...car is just too small to pull that much weight safely.
I had two different 2500 HD trucks both with 494 gas engines and allison 5 speed transmissions....
The smallest truck I used which works ok was a 2000 Dodge Dakota. Extended cabs are more stable.
Now I do not tow as much so I have a 2001 Tahoe but I put all new bilsteins on it, near rear springs, bigger rear sway bar, and air bags. They can handle 5,000 lbs and it is stated on the back bumper area. Fortunately the buicks are fairly light.
I think most readers that respond to your question would agree especially if they have as much trailering experience as I have.
Don't do it.....

I did have one wreck that was my fault with the Dakota guy stopped real quick in front of me and I had no place to go except over his back end. Dakota crumbled even buckled the frame under the bed.....the Turbo regal did not move on the trailer.
