You're likely to get anything tagged YB (except the Fiat/Honda Fit/VW Golf, those are rare). Upgrade PCs are notoriously unreliable. Maybe you will get a midsize but that would more likely be due to a generous agent than the PC code being there. You'd be better off using a PC that gives a discount.
