I know that there are quite a few Oppos who daily drive classics (say, 20-25 years or older), but I suspect that many (most?) are able to do this because they can wrench. I can't wrench, which is why the idea of daily driving a modern classic like the W124 is a little scary.
So why can't I wrench? Well, for starters, I don't have any wrenches, hah. More to the point, I don't have a garage (I live in a downtown condo) and don't know anyone with a garage that I can borrow. As well, I'd probably describe my mechanical knowledge as "barely adequate". Miles ahead of your average driver, but miles behind many Oppos. I'm willing to learn the basics, but learning is doing and if that's my goal, I should get an old Bug, or something, to start with, rather than a far more complicated W124.
I think in part this is because we often learn mechanics at our father's knee, and while my dad knew his cars and was an excellent driver (he owned a 1967 Austin Healey 3000), he always paid a shop to do the off-warranty work, and never did anything beyond basic owner's maintenance (fluid top ups, wipers, bulbs, etc.). I suppose he was able to afford it, and preferred to spend his free time with his family.
So are there any Oppos out there who DD a classic and are, due to circumstance, forced to rely on their local independent garage or specialist? If so, do you have or did you need to acquire basic tools and knowledge to fix common roadside breakdown problems? Do you find the costs of ownership to be prohibitive, or justifiable due to the love for the car?
