I would suggest you think things through a bit more, because I'm about to blow more holes in your theory than Bonnie & Clyde's Ford... "Worth more" means nothing over a span of time unless you consider inflation and costs incurred during that span. Purchase price of a new '93 Cobra, around $21,055 loaded-up (I got that off the window sticker of my '93 Cobra that I special-ordered new, triple-black with every possible option except leather, as I wanted an all-black interior, car is still in the wrapper with 32 original miles..), plus tax $22,318 (was 6% at the time). NOW, as Jethro would say, let's do some cyphering... Adjust for inflation, $22,318 in 1993 dollars equals $30,224 today, using the U.S. CPI Add in keeping collector car insurance on it (far cheaper than traditional auto insurance). Trying to scale this for inflation is too damn complicated, so I'll just be nice and conservative.. $300/year X 13 years = $3,900 Of course, the car will go to hell in no time unless you air condition and heat the storage unit, or garage that it lives in. That costs money over 13 years, not to mention the space it occupies, but I'm not going to nit-pick here, I'm going to ignore that. I'm also going to ignore care and upkeep, which they require even when you're not driving them... Just using inflation-adjusted purchase-price, and insurance, you've got roughly $34,000 tied up in the car, assuming that you already had the space available, already had it climate-controlled, and don't place a value on your own time and labor... Now, tell me how much money you'll make today by selling that brand-new '93 Cobra... Do you think you can even break-even?? I don't truly think you'd be able to eclipse the $30K barrier myself... And I used MSRP for this exercise, not MSRP + some ridiculous dealer mark-up..., and I own one of the very cars you indicated would have been a "good investment". The forecast for a run-of-the-mill Fox platform 5.0 GT or LX would be FAR UGLIER, as even a brand-new in-the-wrapper loaded-up Fox GT convertible, when/if you find one, doesn't fetch much more than $20K in today's market, and they cost in the $17K-21K range MSRP between 1987 & 1993.
