I have owned over 50 vehicles in my 58 years of driving and the newer cars win over the classics. The classics are nice and do appreciate but they are costly to maintain. I had a 69 Corvette 427 Roadster with only 27,000 miles when I purchased it. I only used it in the summer months putting on less than 2000 miles and there wasn't one summer that I spent less than $2000 on repairs. I sold the car in 1995 for $22,000 and the car now is worth about $60,000. So I would have made an extra $38,000 right? Wrong! Take in consideration that it cost you $2000 a year for the last 23 years,which really is a conservative number to keep a Corvette in good condition. Most likely a Corvette that old would have to be painted which would run between $8,000 and $10,000. Another thing to consider if you get a second car is the cost of insurance. Even if you take the car off the road on still will need to have insurance coverage on the Volvo and also on the second car. I'm not adding these numbers but for sure we are over spending. I hope I didn't take the wind from under your wings.
Good Luck
