One of my school mates managed to drive her Capri Mk 1 backwards through a lamp post on the most gentle of bends you could imagine.
The modern equivalent of that is rearranging the back end of a 3-series BMW. Using a lamp post.
I know what you mean but I found my Capri very predictable once you were familiar with it. People used to say about loading the boot for better handling but part of the fun was knowing when the rear was going to break loose, to the point of inducing deliberate power slides mid bend. (I was young and invincible at the time).
Turn the nanny toys off on my 430 BMW and with a bit too much enthusiasm it will snap out of line and things can go wrong very very quickly.
As a serial Capri owner, I agree. They have a couple of characteristics that need to be accounted for: the front and rear roll at different rates, and the front structure is a bit floppy. What's needed is more rear roll stiffness(but not, under any circumstances more spring rate than new, standard single-leaf springs), strut and chassis braces plus struts that don't bend in use(the real reason why the 2.8i Bilstein is preferable). Once you've done that, the need for getting the car settled into a bend early and not changing the steering is reduced. That's a good way to make safe, fast progress in
anything.
They don't need a lot of tyre either; a four cylinder car has a lovely progressive feel on 185/70 13s, and will switch to a four wheel drift at 70mph on a big roundabout, for as many circuits as you like. Not that I've ever done that you understand
