I owned two at the same time for several years -- a 1968 MGB GT (hatchback) and a 1969 MGB (roadster). I drove them both as my only cars for over 20 years. Unfortunately, I destroyed the GT on the freeway 5 years ago, and sold the other one about 3 years ago because my wife was nervous I would kill myself on the freeway with this small convertible. I drive an Acura 3.2 TL now and absolutely love it.
But there is something very special about owning, driving, and maintaining an MGB, especially an early one (pre 1974 when they went rubber bumper and the ride height got too high). I want to buy another one (1967 roadster with metal dash) when I retire in a few years. My experience is that they are very reliable and hardy, including the Lucas electronics which never gave me any trouble. Love the wire wheels, sleek design, low ride, and exhaust note. Damn, I'm wanting another one now ...
