He has two points . First about the money pit. Yes the parts for these cars are high and are going up all of the time. But once the car is running unless you are someone into concours restoration, you should be able to use it without constant repairs and expensive parts. But the really good side is that they are simple enough that most people can do their own repairs and replace parts, saving a ton of money in the process.

But then you may also want to compare the cost of parts for a modern auto with our British parts, probably not a lot of difference in price.
As to the safety I believe that a car is only as safe as the driver. So if the driver is wild and unsafe then even the best car isn't going to help a lot. Drive defensively and maybe even a bit more defensively if you really believe they are not as good as today cars. That may just give you the edge in never having an accident, whether it is your fault or not. One more point about the safety, there is a lot more steel in these cars than in more modern ones. Think about that strong box and X frame underneath that body, not to mention that tractor (Massey Fergeson)engine sitting up front.
For me I will continue to drive my TR's as safely as possible and enjoy the hell out of them.
