I forgot to mention some generalities about test drives (BlackCivic & Nemesis).
It's anybody's guess as to when the CRZ will hit the dealers' lots. We'll know over the coming (many) months.
Getting a test drive is all about how you "qualify" in the dealer's eyes. When a dealer/salesperson
qualifies you (ie sizes you up), he/she assesses how serious you are about buying as well as your ability to pay. If you look like a time-waster, you're not gonna get a drive. If you look like you have no chance of getting financed, you're not gonna get a drive. When a car is very new and in-demand (like the CRZ will probably be in the first months), test-drives become that much harder to get. If a salesperson is eager to get a sale, they'll be more willing to let anyone take a drive. Sadly, an in-demand car like the CRZ in the first months of availability won't have any problems finding interested buyers. If you're really young and don't look "like a live one", be firm in asking for a drive - if you're serious.
If a dealer doesn't want to let you drive something, go to another dealer. There are plenty of dealers out there.
