I bought a 1966 Chevelle with a 350 engine and an automatic transmission. I feel like it’s going to explode, even at only 55 MPH. Do you have any suggestions?

I brought my 1966 Mercedes Benz 250SE into my regular repair shop for an oil and filter change. They replaced the oil with fully synthetic oil and now I’m finding small puddles of oil on my garage floor. Is it just a coincidence that these leaks began right after they changed the oil?

I’ve decided to buy a vintage car but I’m having trouble deciding what I should get. I really like the styling seen in the mid to late 1930s. The problem is, I don’t think a ‘30s car is practical for today’s streets or highways. What should I do?
