Well obviously your car was a lemon but that's not representative of the brand or even the product. You gotta do what you gotta do but there must be a reason you went for the F30 in the first place?
You take your chances with any purchase - you can get a lemon or a tasty apple. By some crazy chance, I'm sitting in a house with two broken Bosch appliances, a dishwasher and a washing machine that cost a combined £1400. Doesn't mean Bosch make rubbish or that I'll never buy a Bosch Logixx dishwasher again. It just means I got a lemon ... or two in this case
If I were you, I'd get another F30
