You need to decide what you want from the car. Is it your daily or a weekend toy? Are you wanting reliability or are you not concerned with breakage? Start with bolt-on's first i.e, cold air intake, exhaust etc. Those can always be undone if you don't like it.
In 60 years when most are gone, they'll be worth as much as they sold for orginally. My 94 Z28 I brought new will be 30 years old next year. The car is in perfect condition but only worth about $12,000.00 to the right buyer.It’s just a weekend cruiser not gonna be a daily at all it’s way too nice for that my main thing is does everyone think these cars are gonna go way up in value as most of them are modified and miled out
