That's a tough call.
Shelby only produced around 562 cars the first year 1965. Then into the thousands every year after until 1970 when only around 636 some odd cars were sold. If you compared year by year, I believe Shelby production far exceeds Saleen mustang production however Saleen is still going strong now.
OK,
look at it this way. From 1965-1970 Shelby produced around 14,400 cars.
From 1984-2003 Saleen has produced around 7,475 cars.
He is pumping out the 05's, I think I heard production stopped around 1,300??? Dennis, Mike??
Anyway, Saleen will never have the race history success that Shelby had. It would be better for collector status if he went out of business soon but I will be a very old man by the time my S351 is worth anything what a 1967 GT500 is worth today. Much better off buying property.
ok, crazy but look. A 1967 GT500 retail price $4195. Let's just say a decent 67GT500 driver can fetch around $125-130k right now. I know there are some that are less and more ( Barrett Jackson ) but I'm just averaging. That's a 3000% change in price.
My sticker on my S351 was $58k back in 1995. If you apply the same nums in 30 years you could say a S351 could go for $1,800,000. Nuts huh? I dunno. I say go buy a house.
Later.
