OK, well this is ABSOLUTELY a matter of opinion. How bad do you want an A12 car. I wanted one REALLY REALLY bad.
I have a real A12 Bee and I really don't consider the hood removal/install to be a PITA. Honestly, I feel lucky to have that car. If you won the lotto, would you complain about paying the taxes? If you were elected President, would you complain about wearing a tie? If you're lucky enough to get a real lift off hood car, you shouldn't complain about the "inconvenience" of the hood. The first time you open that 6 pack, you'll forget all about your concerns over the hood. Seriously.
I use my car for 2 purposes: general cruising AND local car shows. For me, you know what the worst part is? When I go to a show, I like to set the hood up on the prop rods. People are always willing to help but they always put their thumbs on the hood when guiding the hood on the rods. Drives my F***** nuts but I can't say anything because they are helping me. I just say Thank you. Honestly, for me that's the worst part.
I'm 55 too and I'm not a build guy. But for me, removal and install are very simple. 1 man job. No problem. I always store the hood on the roof using a VERY soft, thick blanket. I owned the car for 8 years now. No scratches.
Buy the car. You won't regret it.
