Just fantasizing about this list, I personally would keep the Bronco and the Datsun, which are something I've been saving up for. I'd have to keep the jag or ferrari to go swag around town in. I'd sell a few cars to pay off my debts, a few cars to make some investments, a few cars to buy some toys for myself, and save the rest to sell later.

My advice though, which I'm sure you are getting a ton of, is obviously don't listen to your parents. Their advice is kind pulled out the ass sounding and a bit controlling sounding. Selling everything would be stupid, but so would keeping everything. You gotta take into account storage costs of a ton of cars. The ones that will go up in value the most are also going to need proper security and storage and make sure you have some form of insurance on them in case the places falls into a sinkhole. When looking at their appreciation over ten years, you also gotta account for the storage costs for those 10 years.

I'd say keep a couple that you really like, ones that don't need any further investment. Save a couple that have the best chance of appreciating a lot in value. Other than that some sound financial investments from your financial planner are going to make you a lot of money in the long run. A couple of these cars being sold will give you some education or job training, paid in cash, something a lot of people pay on for decades. A couple more will give you a nice savings account for emergencies, something I personally have never had. A couple more will give you the funds to fix up the ones you keep into reliable transportation or to buy and fix up some other reliable transportation of your choice, times two. A couple more will give you some investments, get a IRA or whatever your adviser says and make the max contributions for a few years, invest in some other things, and in 10, 20, 30 years you will have a fat fuckin bank account. And of course in memory of your uncle save one of the cars to be some nice garage candy. This is a really great gift that could possibly keep you financially stable for years. I wish one of my relatives had some fucking money, I am broke as shit since the day I turned 18.
