Hi fellow mini owner! For anyone else reading this - I wholeheartedly agree. Do not buy a mini without knowing what you're getting into.
For myself - Mini's were my first two cars, and the second one is the one I'm restoring. For some reason I still don't fully understand my parents encouraged me to own a vehicle with the reliability and structural strength of a wet paper towel.. And if you know me I'm not exactly risk averse. But I love that thing and it's still one of the most fun vehicles I've driven after all this time. It's also possible to rev it out without constantly breaking the speed limit, something that the BMW and my CBR 1000RR both struggle with (CBR gets plenty of track time).
It's been repainted, solid subframe mounts, blue coil springs, adjustable dampers, adjustable brake bias, disk brakes at the front - you name it. Currently planning the build of a 1275GT motor (SW1 cam etc) and planning to use a Motogadget blue unit to solve many of the electrical gremlins. I don't know if it will be a daily or even if I will keep it long (I love building stuff so when its done I start looking for the next thing), but I've always meant to do some mini club cruises.
