Once you decide on a trailer. You will have to consider upgrades.
I drove flatbed tow truck for 5 years. Secured the cars on the bed with chains, wheel straps through the rims and wheel straps. Holding the car by the frame is the worst thing you can do to a car. It feels solid but when that bed or trailer hits bumps it will bang into the chains and oval out holes. If the car dips on the suspension, all good. When it extends up, it will smash into the chains so hard dirt and rust will be sitting on the bed to prove what happened.
E tracks to secure all 4 tires is the best method. Have 3 fail and the car will still be there. This is how all the manufacturers tow the new cars.
Not all new cars, like the Vipers the frames were reinforced to chain them down, some other high-end cars are the same. Axle straps are still the safest and easiest to use besides straps through the wheels if it is possible to do that. Using wheel straps in an enclosed trailer is not always easy, especially for us old guys. I have never had an issue with axle straps over the rear axle and trough the lower control arms...
Vipers are not new cars and I'm not saying this to argue. Only to educate that I've seen the difference and sharing my reasons why I think it's better.
Axles or control arms is almost the same as wheel or tire securement. Either allows the suspension to absorb the bumps in the road. I used to tow alot of Mopars with a strap forward from the K member. This is not bad because it's pretty horizontal, not quite chaining a frame downwards on an angle.
Interested on hearing why you think frame is better.
By the way. E tracks is very easy to use. Especially for "old guys" The system secures onto the track, over the tire, onto the track then a clip is used to change the strap from a vertical pull to a horizontal pull. Which will be a ratchet mechanism any distance away like 2 or 3 feet.
