Well, time for me to throw my 2p worth in here.....
A blanket statement like, "Classics are better than most newer cars"
CAN be true in a few aspects.
Most "classics" are generally higher spec cars of thier line. To give an example, not too many people are going to lovingly restore (or keep in mint condition) a 250cid I-6 2spd automatic 1967 Chevrolet Camaro. But come along with a 1968 Camaro RS with a 350 small block (or even better a 427 big block), 4 spd Muncie, 12 bolt posi diff, Corvette disc brake conversion, Moroso T-104 exhaust, Firebird bonnet with ram air scoop, Tracker suspension upgrades, etc etc etc, it's going to be a MUCH more desireable car (and safer to drive) than a 2006 Toyota Prius.
The only advantage to the Prius will be the fuel mileage. Other than that, the Camaro will accelerate MUCH faster (duh), stop quicker (a LOT more rubber on the road and better brakes to stop it with), handle the corners much better due to the race-inspired suspension, and be MUCH safer in brown trouser moments because of all of the above. It will also survive a "normal" (read 5-35mph) impact much better than the Prius. It will also be much more reliable due to being lovingly restored to new condition with QUALITY parts instead of the "supplied by the cheapest bidder" components cars are made from initially, and the fact that there isn't 20 miles of wiring going to multiply redundant sensors that don't really help that much to begin with. Hence a lot less to go wrong.
Granted, take a 1974 Ford Pinto (it
IS a classic) and put it up against a 2006 Subaru Outback and there's just no comparison. The Scooby will obliterate the pony car in every aspect that makes it a car!!
But to write all classics off as "worse" cars than new is silly. There's still cars being produced today that use drum brakes on the rear that are absolutely no different in design than what was on a 1959 Volkswagen Beetle (read worse than useless). Whereas most of what are considered "classics" in the general sense came with 4 wheel disc brakes standard. Not all. Look at all the American muscle cars. Every single one of them bar the Corvette still had rear drums all the way up into the 90's (Mustang). Then again, when you consider just how much of the braking was done by the rear brakes on one of these monsters, there wasn't much point in the added expense of discs for them.....
But all in all, if someone's going to keep or restore a classic, it's going to be one of the higher spec ones. It will also most likely not fall prey to cancer, because if it was going to, it would have already. Johnny69 is quite the exception here....
And as for safety, you can all have your crumple zones and your airbags. I much prefer a good solid steel frame under my arse to save me. Having been in two rather major accidents, both in my little Chevy L.U.V. truck and quite literally walking away from both (and driving the truck), I can honestly say that either one of them would have hospitalised me and totalled the car had I been in my 2001 Neon. As much as I liked the car, I really didn't fancy my survival chances in a 40mph collision with an immovable object. Whereas that's precisely what happened in my little truck. 40mph collision and I walked away uninjured. Twice.
