Nobody ever answered the first question.
What do you think 14 x 7 Alpina wheels are worth?
Chris and others advocating I keep the 14" wheels, what tires would you recommend for 14 x 7 wheels?

Stan, when I see a vintage car with the right tires on it in person, it just looks 'right' to me. When you go to LRP to see the vintage cars race. Look at the ones that have the fat smooth side-wall Dunlop L's. It just screams, "old race car."
But, you have to decide what's important to you. The driving experience or the look.
The 16's look more racy, and have way more bling. Do you want that LA look?
And of course, what driving experience are you looking for? Are you going to do track days like Duane? Are you going to do hill climbs and autocross? If yes AND you want to keep up with the newer cars, you should
(1) take a Skip Barber high performance driving class to learn how to get the most out of what you have
(2) move up to 16's with some UHP summer rubber, or maybe some DOT R's.
(3) consider a tighter suspension or something adjustable (coil overs and adjustable camber plates up front would be nice)
If you're just going to to quick tours with the E9 crowd, start with step one above and then decide if you want 16's afterwards. If you're not sure, get a set of 16's and stash them away. They're not likely to go down in value.
